I— STUDIES    IN   OMUS   AND   CICINDELA. 

Having  recently  received  a  considerable  series  of  Omus  and  many 
interesting  new  forms  of  Cicindela,  it  seems  desirable  to  draw  up  a 
short  paper  on  the  subject  and  the  opportunity  is  taken  to  give  a 
renewed  systematic  study  of  the  genus  Omus,  which  may  aid  in 
forming  a  more  exact  and  comprehensive  idea  of  the  relative  degrees 
of  relationship  of  its  many  rather  confusing  species  and  subspecies. 

Omus  Esch. 

This  genus,  as  known  at  present,  may  be  divided  into  three 
passably  well  defined  subgenera  as  follows: 

Elytra  oval;  lateral  margins  of  the  pronotum  acute  and  without  setae.  .2 

Elytra  subcylindric,  the  lateral  thoracic  margins  not  so  acute  and  having 
erect  setae 3 

2 — Elytra  with  numerous  very  large  foveae,  which  are  disposed  without 
order  among  the  smaller  punctures  common  to  all  the  species  of  the 
genus;  median  line  of  the  pronotum  dilated  and  foveiform  at  the 
middle.  [Type  and  only  known  species  Omus  dejeani  Reiche]. 

Megomus 

Elytra  with  very  small  and  sparse  foveae  mingled  with  the  punctures; 
median  stria  of  the  pronotum  never  so  dilated  centrally;  coloration 
deep  black  to  slightly  brownish,  apparently  never  metallic.  [Type 
Omus  calif ornicus  Esch.] Omus 

3 — Elytra  punctured  and  with  small  sparse  foveae  nearly  as  in  Omus; 
colors  generally  submetallic.  [Type  and  only  known  species  Omus 
siibmetallicus  G.  H.  Horn] Leptomus 

It  is  not  necessary  to  refer  more  particularly  to  dejeani  and 
siibmetallicus  just  now  and  the  present  study  will  be  limited  to  the 
subgenus  Omus  as  defined  above. 

Subgenus  Omus  Esch. 

Observing  critically  the  very  numerous  taxonomic  forms  of  this 
subgenus,  it  becomes  easy  to  recognize  seven  well  defined  groups 
as  follows: 

Antennae  distinctly  shorter  in  the  female  than  in  the  male;  prothorax 
relatively  narrow,  feebly  sculptured,  deeply  declivous  at  the  sides; 
elytra  having  a  tendency  to  be  broadest  behind  the  middle.  Northern 
coast  regions Group  I

6 — Body    stout,    more    ventricose,    generally    dull    in    lustre.     Sierras. 

Group  VII 

These  groups  are  rather  sharply  delimited  in  structure  and 
general  habitus;  they  will  be  designated  below  by  the  principal 
species  in  each  case. 

Group  I   (audouini). 

The  species  are  moderately  numerous  and  are  confined  to  the 
more  northern  regions,  perhaps  more  especially  near  the  coast, 
but  of  this  I  am  not  sure  in  all  cases. 

Body  ventricose,  the  hind  body  alwa'ys  very  much  wider  than  the  pro- 
thorax 2 

Body  very  slender,  the  elytra  more  subcylindric  and  but  little  wider  than 
the  prothorax 7 

2 — Elytral  punctures  strong,  irregularly  subconfluent,  generally  without 
intermingled  minute  punctures 3 

Elytral  punctures  feebler,  more  uniform  in  distribution  and  with  inter- 
spersed minute  punctures 6 

3 — Elytral  punctures  toward  the  suture  feebler  and  finely  lineiform  at 
the  bottom;  body  massive,  the  prothorax  larger,  rather  wider  than 
long,  the  base  rather  strongly  bisinuate;  surface  between  the  more 
rugulose  apical  and  basal  regions  almost  smooth,  opaculate,  with 
very  fine  anastomosing  lines  and  very  minute  punctulation;  elytra 
widest  slightly  behind  the  middle;  antennse  rather  stouter  basally 
than  in  the  other  species  of  the  group.  Length  (c?)  16.0  mm.; 
width  6.0  mm.  California  (Shasta  Co.), — Nunenmacher. 

ambiguus  Shpp. 

Elytral  punctures  more  rounded,  deeper,  not  lineiform  at  the  bottom  at 
any  part  of  the  surface 4 


AND    ClCINDELA  3 

4 — Hind  tarsi  ( 9  )  shorter,  about  as  long  as  the  tibiae;  prothorax  narrow, 
as  long  as  wide  even  in  the  female,  the  base  more  transverse  and 
more  broadly  and  feebly  bisinuate;  surface  with  the  anastomosing 
lines  rather  distinct,  the  minute  punctulation  evident.  Length 
(d71  9  )  14.0-15.5  mm.;  width  5.0-5.5  mm.  Oregon  and  Washington 
State.  Rather  abundant audouini  Rche. 

Hind  tarsi  ( 9  )  much  longer  than  the  tibiae 5 

5 — Body  small  and  notably  slender,  of  a  facies  and  in  sculpture  nearly 
as  in  audouini  but  with  shorter  and  more  slender  antennae;  prothorax 
nearly  similar,  narrow,  as  long  as  wide  and  nearly  similar  in  the 
two  sexes  as  in  audouini.  Length  (cf  9  )  12.8-13.2  mm.;  width 
4.4-4.8  mm.  Oregon parvulus  Csy. 

Body  large,  very  stout  and  massive;  antennae  notably  short  in  the  female; 
prothorax  much  larger  and  broader  than  in  the  two  preceding,  wider 
than  long,  the  base  transverse  and  barely  perceptibly  bisinuate,  the 
surface  opaculate  and  with  fine  anastomosing  lines  and  minute 
punctulation  as  in  audouini;  elytra  broad,  rather  feebly  convex 
medially,  widest  at  the  middle  and  with  the  punctures  more  evenly 
circular  and  much  deeper  than  in  any  other  of  the  group,  perforate, 
the  interspaces  rather  shining,  only  feebly  alutaceous  and  without 
trace  of  minute  punctulation.  Length  (  9  )  17.0  mm. ;  width  6.3  mm. 
Northern  California  (without  record  of  more  definite  locality). 

rugipennis  n.  sp. 

6 — Body  rather  shorter,  relatively  broader  and  moderately  convex,  the 
hind  tarsi  much  longer  than  the  tibiae  in  both  sexes;  prothorax 
relatively  larger  and  broader  than  in  audouini  or  parvulus,  though 
nearly  similarly  sculptured ;  base  transverse  and  very  feebly  bisinuate ; 
elytra  widest  at  the  middle,  the  punctures  rather  small  and  well 
•  separated  internally  and  also  rather  more  than  usually  obsolete 
near  the  humeri,  which  are  distinctly  convexo-declivous  as  usual; 
interspersed  minute  punctulation  very  obvious.  Length  (cf  9  ) 
13.8-15.8  mm.;  width  5.3-5.9  mm.  California  (Del  Norte  Co.),— 
Nunenmacher humeroplanatus  \V.  Horn 

Body  larger,  more  elongate  and  more  convex,  relatively  not  so  ventricose 
as  in  audouini,  the  prothorax  much  larger,  very  little  wider  than  long, 
.  opaculate,  the  fine  anastomosing  lines  evident;  base  transverse, 
broadly  and  very  feebly  bisinuate;  elytra  one-half  longer  than  wide, 
barely  one-half  wider  than  the  prothorax,  widest  a  little  behind  the 
middle;  surface  very  convex,  with  the  micro-granulation  strong  and 
more  conspicuous  than  in  any  other  species,  almost  obliterating  the 
minute  punctulation,  the  punctures  rather  coarse  and  confused  but 
unusually  shallow  and  generally  with  their  bottom  finely  lineiform 
by  transverse  light,  the  scattered  foveae  very  inconspicuous,  much 
less  evident  than  in  the  preceding;  hind  tarsi  but  little  longer  than 
the  tibiae.  Length  (cf )  16.0  mm.;  width  5.9  mm.  California  (Shasta 
Retreat,  Siskiyou  Co.) solidulus  n.  sp. 

7 — Form  and  habitus  radically  different  from  any  of  the  preceding,  due 
to  the  very  elongate  cylindric  outline ;  front  nearly  smooth  and  without 
punctures  between  the  foveee;  prothorax  about  as  long  as  wide, 
sculptured  nearly  as  in  audouini,  the  transverse  subbasal  groove

rather  deep,  the  sides  at  its  ends  feebly  constricted;  base  transverse, 
very  feebly  bisinuate;  elytra  four-fifths  longer  than  wide,  scarcely 
more  than  a  fourth  wider  than  the  prothorax,  the  sides  parallel, 
barely  arcuate  except  basally  and  apically,  finely,  sparsely  punctate 
and  with  rather  distinct  foveae.  Length  (cf)  13.7  mm.;  width  4.25 
mm.  California  (Lassen  Co.), — Nunenmacher. 

cylindricus  \V.  Horn 

I  am  unable  to  persuade  myself  that  any  one  of  the  above  forms 
has  less  than  specific  value  and  would  not  know  how  to  make  the 
combinations;  they  are  undoubtedly  distinct  among  themselves 
and  by  no  means  so  closely  allied  as  in  some  other  groups,  where 
many  of  the  forms  obviously  have  rather  less  than  full  specific 
weight.  At  first  it  seemed  as  though  parvulus  might  be  no  better 
than  a  subspecies  of  audouini,  but  the  recent  discovery  of  the 
female,  with  its  short  delicate  antennae  and  long  hind  tarsi,  appar- 
ently determines  its  specific  value. 

Alluding  to  the  general  question  of  species  in  the  genus  Omus, 
it  is  quite  beyond  my  power  of  comprehension  to  understand  how 
any  student,  having  within  him  a  moderate  development  of  the 
sense  of  proportion  and  having  before  him  such  forms  as  cylin- 
dricus* IcBvis,  cribripennis,  parvicollis  and  edwardsi,  for  instance, 
could,  with  all  their  manifold  peculiarities  of  structure  and  facies, 
hold  them  to  be  of  no  greater  taxonomic  weight  than  mere  sub- 
ordinates of  a  single  species.  Such  an  opinion,  I  am  thoroughly 
convinced,  could  only  arise  from  a  misconception  of  the  term  species 
from  a  pragmatic  viewpoint. 

Group  II  (calif ornicus). 

The  various  units  in  this  group  hold  much  more  truly  to  the 
typical  form  than  in  the  preceding  and,  though  recognizable  on 
actual  comparison,  some  of  them  may  be  rather  difficult  to  decipher 
from  descriptions,  however  full  of  detail.  They  fall  under  three 
rather  distinct  stem  forms  as  follows : 

*  The  original  name  given  this  species  was  angusto-cylindricus.  The  infliction  of 
such  unwieldy  names  as  this  and  intermedia- pronolalis  upon  our  nomenclature  may 
betray  a  lack  of  sympathetic  respect  for  our  powers  of  endurance  in  quoting  them,  or 
else,  perhaps,  they  may  not  be  intended  to  be  permanent  in  their  entirety  as  specific 
names.  I  have  assumed  the  latter  to  be  the  correct,  because  the  more  rational, 
assumption,  and  have  therefore  omitted  the  unnecessary  qualifying  part  of  these 
hyphenated  specific  names. 


AND    ClCINDELA  5 

Body  rather  stout,  strongly  convex,  the  sides  of  the  prothorax  converging 

and  but  slightly  arcuate  from  near  the  apex  to  the  base 2 

Body  much  narrower,  the  elytral  punctures  denser;  prothorax  with  the 
sides  subparallel  and  broadly  arcuate  in  more  than  apical  half,  then 
rapidly  more  convergent  to  the  base;  copulatory  spicule  in  mimus 

nearly  as  in  californicus,  concealed  in  the  type  of  sculptilis 3 

2 — Form  only  moderately  elongate,  ventricose,  shining;  head  narrower 
than  the  prothorax  in  both  sexes,  rugose  throughout,  the  median 
part  of  the  front  without  punctures;  prothorax  obtrapezoidal,  about 
as  long  as  wide,  a  little  wider  in  some  females,  very  deeply  vermicu- 
lato-rugose  throughout;  elytra  oval,  barely  more  than  one-half  longer 
than  wide,  widest  at  the  middle,  the  coarse  strong  punctures  well 
separated  suturally,  close  and  subconfluent  laterally;  copulatory 
spicule  obliquely  and  almost  rectilinearly  truncate  externally  at 
tip,  the  latter  only  moderately  prolonged.  Length  (cf  9  )  14.0— 
16.8  mm.;  width  5.0-5.9  mm.  California  (about  San  Francisco 

Bay) .     Abundant californicus  Esch. 

A — Similar  to  californicus  but  rather  larger  and  more  elongate,  the 
elytra  three-fourths  or  more  longer  than  wide;  prothorax  always 
wider  than  long  by  a  fourth  to  third  of  its  length  in  the  female, 
in  which  sex  it  is  more  than  three-fourths  as  wide  as  the  elytra; 
copulatory  spicule  not  exposed  in  the  single  male.  Length  (d71  9  ) 
15.5-17.5  mm.;  width  5.4-6.0  mm.  California  (locality  not  recorded 
but  probably  near  San  Francisco).  Three  examples. 

vermiculatus  n.  subsp. 

Form  still  more  abbreviated,  ventricose,  much  smaller  in  size,  rather 
shining;  head  barely  narrower  than  the  prothorax,  rugose  throughout; 
prothorax  as  in  californicus  but  with  the  vermiculiform  rugosity 
coarser  and  rather  less  deep,  becoming  in  fact  rather  feeble  very 
near  the  median  stria;  elytra  very  evenly  oval  and  widest  at  the 
middle,  with  strongly  arcuate  sides,  the  punctures  coarse,  deep  and 
rather  close-set,  more  evenly  spaced  throughout  than  in  californicus; 
copulatory  spicule  very  different,  narrower  and  more  prolonged 
apically  and  evenly  arcuate  in  curvature,  not  at  all  truncate  exter- 
nally. Length  (cf)  13.0  mm.;  width  5.0  mm.  Oregon  (Josephine 

Co.), — -Nunenmacher oregonensis  Csy. 

3 — Body  rather  narrow  and  elongate,  moderately  convex,  moderately 
shining,  more  densely  sculptured  than  californicus;  head  narrower 
than  the  prothorax,  very  closely  and  strongly  rugose  throughout; 
prothorax  wider  than  long,  the  vermiform  rugae  very  deep  and  finer 
than  usual  in  californicus;  elytra  oblong-oval,  two-thirds  longer 
than  wide,  the  sides  only  moderately  arcuate,  widest  near  the  middle, 
coarsely,  deeply  and  very  uniformly,  closely  and  almost  subcon- 
fluently  punctured  throughout,  each  puncture  having  a  more  dis- 
tinct granule  at  its  anterior  end  than  in  californicus  and  rather  less 
coarse  and  more  elongate  in  form.  Length  (c?)  15.5  mm.;  width 
5.4  mm.  California  (north  of  San  Francisco).  A  single  example. 

sculptilis  Csy. 

A — Smaller  and  still  narrower  than  sculptilis  but  otherwise  very  similar, 
except  that  the  head  is  about  as  wide  as  the  prothorax,  the  rugae 


6  MEMOIRS  ON  THE  COLEOPTERA 

of  the  latter  not  so  fine  and  the  elytra  more  evenly  elongate-oval 
and  less  oblong;  they  are  also  more  convex  and  have  the  punctures 
more  clearly  separated  and  without  such  evident  acute  granules, 
being  more  as  in  calif ornicus.  Length  (cf)  14.0-14.3  mm.;  width 
4.8-5.1  mm.  California  (the  type  bears  no  more  accurate  indica- 
tion of  locality,  but  another  example  at  hand  was  collected  near 
San  Francisco) mimus  Csy. 

Additional  material  serves  to  show  that  sculptilis  should  be  given 
higher  relative  value  than  previously  accorded  it,  the  narrow  form 
of  body  and  peculiar  outline  of  the  prothorax,  still  more  accentu- 
ated in  mimus,  serving  to  isolate  it  from  calif  ornicus  at  a  glance; 
mimus  is  evidently  closely  related  but  is  much  more  slender  in  its 
anterior  parts.  The  types  of  vermiculatus  were  received  under  the 
name  lecontei. 

Group  III  (edwardsi). 

The  large  stout  forms,  with  very  oblique  and  nearly  straight  sides 
of  the  prothorax,  constituting  this  group,  are  well  known  to  all 
collectors.  They  are  apparently  very  circumscribed  in  habitat, 
being  confined  to  that  part  of  the  Sierras  in  and  near  Placer  Co. 
The  elytra  are  frequently  slightly  brownish  in  tint,  apparently  not 
always  wholly  because  of  immaturity.  Having  been  fortunate 
enough  to  personally  capture  a  single  example  of  the  true  edwardsi 
on  the  shore  of  Lake  Tahoe,  I  feel  better  prepared  to  separate  the 
various  units  in  a  more  definite  manner,  for  in  most  collections  a 
number  of  distinct  modifications  of  the  stem  form  figure  under  the 
name  edwardsi,  which  in  its  typical  development  inhabits  only  the 
region  near  Lake  Tahoe.  There  are  two  distinct  types  in  the  group 
as  follows: 

Elytral  sculpture  coarser  and  denser,  the  punctures  rather  close-set 
suturally,  becoming  densely  crowded  on  the  flanks 2 

Elytral  sculpture  much  finer,  the  punctures  everywhere  notably  small, 
widely  separated  suturally  and  never  densely  crowded  on  the  flanks. .  3 

2 — Form  oblong-elongate,  only  moderately  shining,  black;  head  finely 
and  rather  feebly  rugulose,  the  front  between  the  impressions  nearly 
smooth  but  without  punctures;  prothorax  relatively  smaller  than 
usual  and  less  transverse,  somewhat  as  in  edwardsi,  only  a  third  to 
two-fifths  wider  than  long,  finely  and  closely  vermiculato-rugulose 
throughout;  elytra  two-thirds  to  three-fourths  longer  than  wide, 
more  oblong  than  usual,  the  sides  less  arcuate,  widest  at  the  middle 
and  less  than  one-half  wider  than  the  prothorax.  Length  (cf  9  ) 
17.5-18.0  mm.;  width  6.0-6.6  mm.  California  (Placer  Co.). 

montanus  Csy. 


OMUS   AND    ClCINDELA  7 

A — Form  nearly  as  in  montanus  but  rather  more  slender  and  frequently 
brownish  in  color,  the  sculpture  similar  throughout;  prothorax 
shorter  and  more  transverse,  relatively  more  narrowed  at  base; 
hind  tarsi  shorter  and  more  slender.  Length  (9  )  16.8-17.8  mm.; 
width  5.8-6.0  mm.  California  (Placer  Co.).  One  specimen 
received  at  the  same  time  as  the  preceding  and  another  from  a 

different  source brunnescens  Csy. 

3 — Form  stouter,  the  hind  body  shorter,  more  dilated  and  with  more 
arcuate  sides  than  in  montanus,  very  faintly  brunnescent;  head 
similar  but  with  still  feebler  rugulosity;  prothorax  only  a  fourth 
wider  than  long,  finely  rugulose  and  with  some  extremely  minute 
punctulation,  the  anterior  transverse  impression  conspicuous;  elytra 
scarcely  more  than  one-half  longer  than  wide,  very  evenly  oval, 
with  evenly  arcuate  sides,  widest  at  the  middle;  punctures  fine  and 
well  separated  even  on  the  flanks.  Length  (c?)  17.0  mm.;  width 

6.2  mm.     California  (Lake  Tahoe) edwardsi  Cr. 

A — Larger  than  edwardsi  but  otherwise  very  similar,  except  that  the 
prothorax  is  slightly  more  transverse  and  the  fine  rugulosity  of 
the  pronotum  distinctly  stronger,  with  more  shining  interspaces; 
labrum  with  the  median  lobe  strong,  more  abruptly  truncate  at 
the  tip  of  the  lobe  than  in  edwardsi;  elytra  more  elongate  though 
evenly  oval,  with  arcuate  sides,  the  punctures  rather  small  and 
well  separated  but  stronger  than  in  edwardsi,  the  scattered  foveae 
much  more  distinct  than  in  that  species,  where  they  are  unusually 
feeble  and  indistinct.  Length  (cf1  9  )  15.8-18.5  mm.;  width  5.5- 
6  7  mm.  California  (Placer  Co.).  [0.  lucidicollis  Csy.]. 

lobatus  Csy. 

In  the  above  described  topotype  of  edwardsi,  the  seta  at  each 
side  of  the  epistoma  is  at  the  middle  of  the  length  and  there  are 
four  long  stiff  setae  above  each  eye,  a  condition  which  is  however 
unstable  in  the  genus.  Lucidicollis  cannot  be  maintained  even 
as  a  well  denned  variety  and  must  be  united  with  lobatus. 

Group  IV  (parvicollis) . 

The  general  habitus  in  this  group,  due  to  the  very  elongate  form, 
small  prothorax  and  fine  sparse  elytral  punctures,  is  altogether 
different  from  that  of  any  other  type  of  the  genus;  the  various 
units  seem  to  be  confined  to  the  southern  Sierras,  in  and  near 
Tulare  Co.  Those  known  thus  far  are  the  following: 

Body  very  slender,  elongate,  convex,  deep  black  and  subopaculate;  head 
subequal  in  width  to  the  prothorax,  moderately  though  distinctly 
rugose,  the  median  part  of  the  front  smooth  and  not  punctate; 
apical  part  of  the  mandibles  very  long  and  slender;  prothorax  as 
long  as  wide  (cf )  to  slightly  wider  than  long  (9  ),  barely  more  than 
half  as  wide  as  the  elytra,  the  sides  converging  from  near  the  apex 


8  MEMOIRS  ON  THE  COLEOPTERA 

to  the  base  and  feebly  arcuate;  base  feebly  lobed  medially;  surface 
opaque,  with  very  fine  anastomosing  irregular  lines  and  fine  anterior

The  copulatory  spicule  throughout  is  of  the  same  type,  long,

more  nearly  a  distinct  species  than  a  subspecies. 

Group  V  (lecontei). 

In  this  group  the  body  is  decidedly  elongate,  rather  strongly 
sculptured  and  usually  with  shining  integuments;  it  occurs  in  the 
coast  regions  from  Monterey  to  northern  Oregon,  so  far  as  now 
represented  in  my  collection,  and  consists  of  four  species  and 
several  subspecies  as  follows: 

Elytra  widest  before  the  middle,  gradually  arcuately  narrowed  thence  to 
the  acute  apex;  labrum  subtruncate;  body  slender;  lateral  margin  of 
the  prothorax  fine  and  but  slightly  reflexed,  attaining  the  base;  head 
and  pronotum  rugulose  throughout.  Length  15-16  mm.  Cali-

been  able  to  note  its  conformation  in  the  singular  borealis  section, 
which  is  of  more  northern  distribution  and  quite  distinct  in  several

Group  VI   (sequoiarum) . 

In  some  of  the  species  of  this  group  there  is  a  decided  sexual 
inequality  in  the  antennae,  similar  to  that  so  markedly  developed 
in  the  audouini  group.  The  various  species  and  subspecies  seem 
to  be  confined  to  the  Sierras,  from  Sierra  to  Mariposa  Co. ;  they  are 
generally  of  rather  stout  build  and  with  opaculate  or  feebly  shining 
integuments,  but  are  less  ventricose  than  in  the  Icevis  group.  So 
far  as  known  to  me  they  may  be  differentiated  as  follows: 

Body  decidedly  elongate  and  of  larger  size,  strongly  convex.  Head 
narrower  than  the  prothorax,  rugulose  throughout,  the  impressions 
feeble,  the  front  between  them  less  coarsely  but  distinctly  rugulose 
and  without  punctures;  labrum  moderately  and  arcuately  lobed; 
prothorax  about  as  long  as  wide  (c?)  or  wider  than  long  (9  ),  ob- 
trapezoidal,  widest  near  the  apex,  with  the  oblique  sides  but  very 
feebly  arcuate  and  coarsely  and  strongly  re  flexed,  the  margin  at- 
taining the  base,  which  is  transverse,  very  feebly  bisinuate;  surface 
finely  and  very  moderately  vernacularly  rugose,  equally  throughout; 
elytra  very  evenly  elongate-oval  and  strongly  convex,  three-fourths 
longer  than  wide,  widest  exactly  at  the  middle,  the  punctures  small, 
not  deep,  aciculate  and  widely  separated,  but  little  larger  and  still 
well  separated  on  the  flanks,  the  foveae  small  and  very  inconspicuous.

prothorax  larger,  wider  than  long  in  both  sexes,  the  sides  similarly 
coarsely  reflexed  but  more  arcuate,  the  rugulosity  rather  coarser; 
elytra  similar  in  their  regularly  elongate-oval  form  but  with  the 
punctures  very  coarse  and  deep,  separated  by  about  their  own 
diameters  and,  on  the  flanks,  not  coarser,  as  is  usual,  but  smaller 
and  more  close-set  though  not  in  mutual  contact;  hind  tarsi 
notably  long.  Length  (cf  9  )  17.5-21.0  mm.;  width  6.0-7.2  mm.

wrinkled  all  over,  except  the  middle  of  the  front,  which  is  smooth  and 
sparsely  punctate,  the  impressions  feeble;  labrum  moderately, 
arcuately  lobed;  prothorax  wrinkled  throughout  but  not  deeply,  the 
lateral  margin  fine  and  but  slightly  reflexed,  attaining  the  base; 
sides  feebly  arcuate,  moderately  converging  to  the  base;  elytra 
elliptical,  widest  in  front  of  the  middle,  moderately  convex,  closely, 
not  deeply  punctate,  confusedly  so  toward  apex.  Length  17  mm.

I  am  rather  of  the  opinion  that  cribripennis  is  a  species  different 
from  blaisdelli  and  that  confluens  has  higher  value  than  here  sug- 
gested for  it,  but  feel  that  the  modern  tendency  to  combine  rather 
than  to  differentiate  and  to  attribute  structural  differences  in 
related  forms  to  accidental  causes,  should  be  respected  at  least  to 
some  extent.  In  the  females  of  this  group  the  coarse  setigerous

abdominal  segment,  are  rather  better  developed  than  elsewhere. 
The  copulatory  spicule  in  the  few  instances  where  it  is  observable 
without  dissection,  has  a  form  in  this  group  very  different  from 
that  seen  in  the  preceding  groups,  the  apex  being  less  slender  and 
but  very  feebly  curved  downward. 

Group  VII   (Icevis}. 

No  other  group  comprises  within  its  limits  such  marked  diversity 
of  elytral  sculpture  as  this,  for  while  the  prothorax  remains  constant 
throughout  in  its  very  smooth  opaque  surface,  with  scarcely  a  trace 
of  sculpture  except  the  feeble  rugulosity  about  its  periphery,  the 
elytra  may  be  more  coarsely  and  conspicuously  punctured  than  in 
any  other  species  of  the  genus  as  in  compositus,  or  perfectly  smooth, 
with  barely  a  trace  of  any  sort  of  punctuation  as  in  Icevis,  this 
latter  condition  also  being  a  unique  exception  in  the  genus.  The 
body  is  rather  short  and  notably  stout  in  form  and  is  unusually 
ventricose.  The  copulatory  spicule  is  somewhat  as  in  the  cali- 
fornicus  group,  being  subangularly  bent  apically,  the  distal  part 
straight,  but  it  is  more  prolonged  than  in  californicus.  There 
seem  to  be  three  species  and  several  subspecies  as  follows: 

Elytral  punctures  strong,  each  with  an  acute  anterior  granule.  Body 
( 9  )  stout,  convex,  dull  and  sericeo-alutaceous  in  lustre;  head  smaller 
than  the  prothorax,  moderately  rugulose  almost  throughout,  the 
front  not  punctate;  impressions'  feeble;  labrum  strongly  lobed; 
prothorax  large,  much  wider  than  long,  widest  near  the  apex,  the 
sides  only  moderately  oblique  and  feebly  arcuate,  inwardly  arcuate 
at  base,  the  reflexed  margin  moderate,  stronger  posteriorly,  not 
attaining  the  base;  surface  opaque,  finely  but  distinctly,  confusedly 
rugulose  basally  and  apically  and  feebly,  transversely  plicatulate 
laterally;  elytra  less  than  one-half  longer  than  wide,  evenly  oval, 
pointed  apically,  widest  at  the  middle,  much  wider  than  the  pro-

This  group  presents  a  rather'  more  difficult  taxonomic  study 
than  any  other  and  I  have  puzzled  long  over  the  most  probable 
inter-relationships  of  the  various  units.  Horni  is  certainly  a  dis- 
tinct species,  but  whether  the  forms  from  tularensis  to  lams  con- 
stitute a  single  species  or  not,  I  cannot  quite  make  up  my  mind. 
Opacellus  is  a  very  distinct  form,  but  there  is  no  record  at  hand 
concerning  the  altitude  of  its  habitat. 

In  the  above  arrangement  I  have  been  obliged  to  omit  xanti  Lee. 
and  vandykei  and  fuchsi  of  W.  Horn,  not  having  seen  any  authentic 
representatives  of  them.  The  descriptions  of  lecontei  and  inter - 
medius  are  taken  from  the  originals  and  with  reference  also  to  the 
work  of  Mr.  Leng.  In  the  case  of  horni,  its  identity  with  collaris 
is  merely  a  surmise;  the  available  material  in  this  restricted  section 
is  at  present  far  too  small  for  final  judgment.

Cincindela  Linn. 

In  the  longilabris  group,  the  species  allied  to  montana,  having 
the  upper  surface  black,  are  better  defined  than  those  allied  to 
longilabris,  for  they  differ  among  themselves  not  only  quite  radically 
in  sculpture  but  in  tarsal  characters.  The  strong  dilatation  of  the 
first  three  joints  of  the  anterior  male  tarsi  in  this  group  has  been 
noted  many  times;  this,  as  well  as  the  elongate  labrum,  peculiar 
coarse  sculpture  and  bald  front  in  both  sexes,  causes  it  to  be  sharply 
defined  among  the  other  groups.  The  black  species  may  be  known 
by  the  following  characters: 

Elytral  punctures  coarse  and  close,  everywhere  either  in  mutual  contact 
or  densely  and  polygonally  crowded 2 

Elytral  punctures  suturally  smaller,  rounded  and  clearly  separated  by  the 
more  shining  interspaces,  larger  and  denser  laterally;  under  surface 
not  or  barely  noticeably  metallic  at  any  part;  tarsi  very  slender.  .4 

2 — Hind  tarsi  long  and  very  slender,  much  longer  than  the  tibiae  in  both 
sexes;  upper  surface  deep  black,  dull  in  lustre,  the  labrum  (cf) 
entirely  pale,  or  ( 9  )  black,  generally  pallescent  narrowly  along  the 
middle  and  at  the  basal  margin;  prothorax  transverse,  obtrapezoidal, 
dull,  with  deep  transverse  impressions;  elytra  with  a  fine  faint  and 
feebly  bent  median  band  and  a  slightly  pallescent  transverse  apical 
streak;  abdomen  with  slight  metallic  coloration.  Length  (cf  9 )

strong  and  very  acute;  prothorax  very  short  and  transverse;  elytra 
shorter,  the  fine  and  moderately  pale  median  band  more  strongly

dull,  distinctly  biconcave  and  finely,  closely  rugulose,  strongly 
carinate  medially;  prothorax  as  usual,  strongly  transverse;  elytra 
without  pale  maculation,  though  with  the  location  of  the  median 
band  rather  obviously  indicated  by  the  form  of  sculpture;  abdomen 
with  feeble  metallic  glint,  the  apex  ( 9  )  wholly  different  from  the 
preceding,  being  evenly  parabolic  from  side  to  side,  the  middle  of  the 
apex  rather  narrowly  rounded,  with  a  very  minute  and  feeble 
notch,  the  surface  not  impressed;  in  the  male  the  apical  sinus  is 
nearly  as  in  montana;  hind  tarsi  rather  short,  about  as  long  as  the

mm.  Alberta  (Lethbridge), — J.  Harms calgaryana  n.  sp. 

The  above  forms  are  all  unequivocally  specific  in  nature,  differing 
among  themselves  in  important  structural  features.  The  difference 
in  form  of  the  abdominal  apex  in  the  female  of  nebraskana  and 
calgaryana  is  indeed  remarkable.  I  regret  being  unable  to  give  a 
complete  table  of  this  interesting  group ;  so  many  of  the  forms  allied 
to  longilabris  are  unrepresented  in  my  material,  that  it  is  scarcely 
worth  while  to  attempt  a  full  report.  My  previous  statements  in 
regard  to  nebraskana  and  the  Lethbridge  specimens  are  erroneous 
and  were  due  to  the  fact  that  I  did  not  at  that  time  have  the  true 
montana  in  my  collection. 

In  the  nigroccerulea  group  it  is  sufficiently  evident  from  an  ex- 
ample of  robusta  Leng,  which  is  now  before  me,  that  my  feminalis 
does  not  differ  except  varietally,  robusta  being  of  a  dull  sericeous 
green  and  feminalis  blackish-blue,  with  the  same  sericeous  lustre; 
in  the  female  of  both  forms  the  juxta-sutural  shining  depressed 
punctured  spot  near  basal  fourth  is  evident.  In  my  opinion  both 
robusta  and  feminalis  should  be  considered  subspecies  of  the  appar- 
ently larger  nigroc&rnlea. 

The  recent  acquisition  of  the  true  pusilla  of  Say,  enables  me  to 
make  some  more  usefully  definite  statements  than  were  possible 


OMUS    AND    ClCINDELA  1 9 

last  year.  In  the  first  place,  cinctipennis  of  LeConte,  is  a  different 
species  from  pusilla  and  is  not  by  any  means  a  variety;  this  can  be 
seen  at  first  glance  by  reason  of  the  relatively  smaller  head  and  less 
prominent  eyes,  as  well  as  the  paler  coloration  and  stronger  elytral 
sculpture  of  cinctipennis.  I  assume  cyanella  Lee.,  to  be  the  green 
or  blue  form  occurring  in  more  northern  regions  and  having  still 
stronger  and  more  asperate  punctures.  Cyanella  is  a  subspecies  of 
cinctipennis.  Terricola  Say,  still  remains  unknown  to  me.  The 
following  is  a  subspecies  of  pusilla: 

Cicindela  pusilla  ssp.  sayanella  nov. — Form  and  size,  the  broad 
head  and  prominent  eyes  as  in  pusilla,  the  elytra  not  quite  so  sombre 
in  ground  color,  being  very  obscure  coppery-brown,  the  punctures  similar, 
sparse  and  fine,  but  becoming  stronger,  closer  and  metallic  apically; 
the  markings  consist  of  a  slender  and  feebly  arcuate  humeral  lunule,  a 
slender  and  entire  apical  lunule,  inflexed  at  its  anterior  end  and  a  short 
median  marginal  streak,  which  is  obtusely  angulate  internally  at  its 
middle  point;  legs  and  tarsi  (9)  a  little  shorter  than  in  the  female  of 
pusilla ;  truncate  lobe  of  the  last  ventral  more  impressed  than  in  that 
species.  Length  (9)  10.0  mm.;  width  3.4  mm.  (Monroe  Canon, 
Sioux  Co.,  Nebraska.) — Knaus. 

In  both  male  and  female  of  pusilla,  the  elytral  punctures  are  fine 
and  notably  sparse  from  base  to  apex;  the  labrum  is  more  strongly 
lobed  and  tridentate  than  in  the  female  of  pusilla  and  more  nearly 
as  in  the  same  sex  of  cinctipennis.  Sayanella  is  probably  the  form 
indicated  by  Say  as  a  variety  of  pusilla. 

The  following  is  a  distinct  member  of  the  pusilla  group: 

Cicindela  tularensis  n.  sp. — Outline  and  size  nearly  as  in  pusilla, 
the  ground  color  above  obscure  coppery-brown;  under  surface  not  very 
brilliant  metallic  blue-green  throughout,  with  rather  dense  white  hair 
on  the  sterna  of  the  hind  body  and  sides  of  the  abdomen,  the  prosternum 
glabrous,  its  parapleura  sparsely  hairy;  legs  very  slender,  black,  slightly 
metallic,  the  tibia*  and  tarsi  in  great  part  pallescent;  head  rather  small, 
but  little  wider  than  the  prothorax,  the  latter  subquadrate,  only  a  little 
narrowed  behind,  larger  in  the  female,  finely,  densely  sculptured;  elytra 
somewhat  cuneiform,  widest  posteriorly,  with  nearly  straight  sides, 
having  small  sparse  and  very  unevenly  distributed  punctures,  each  within 
a  conspicuous  ocellate  spot,  which  is  blue  centrally  and  gray  peripherally, 
the  foveae  of  the  irregular  subsutural  series  very  small  and  inconspicuous. 
Length  (c/1  9  )  9.5-10.3  mm.;  width  3.3-4.0  mm.  California  (Tulare 
Co.).  Four  examples,  received  under  the  name  lunalonga  var.  tuolitmnce. 

In  one  male  the  pale  markings  on  the  elytra  consist  of  a  very 
slender  humeral  lunule,  a  very  fine  linear  apical  lunule,  rectilinearly 


20  MEMOIRS  ON  THE  COLEOPTERA 

deflected  at  right  angles  anteriorly  and  a  short  medial  submarginal 
streak,  from  the  middle  of  which  proceeds  internally  a  very  fine 
elbowed  band,  which  is  abruptly  much  enlarged  at  its  posterior  end. 
In  another  male  the  humeral  lunule  is  still  finer  and  shorter,  but 
there  is  on  the  disk  before  the  middle  at  inner  fourth,  an  elongate 
dash,  which  represents  the  posterior  end  of  the  long  lunule  of 
lunalonga,  the  other  markings  nearly  as  in  the  first  male.  In  the 
third  male  there  is  no  trace  of  pale  maculation  at  any  part  of  the 
elytra,  which  is  the  case  also  in  the  single  female.  Although  doubt- 
less allied  to  lunalonga,  from  Sierra  Co.,  this  species  seems  to  differ 
in  the  conspicuous  ocellated  elytral  spots,  very  inconspicuous 
foveae  and  very  slender  and  not  "broad"  apical  lunule. 

This  is  the  species  that  I  had  previously  thought  to  be  tuolumnce 
Leng,  from  the  Hetch  Hetchy  Valley,  but  that  is  described  as 
sericeous  green  and  with  the  elytra  not  visibly  punctate.  It  is 
my  opinion  that  we  have  in  the  Sierras  these  three  species,  which 
are  mutually  distinct  and  valid,  but  if  the  final  verdict  be  otherwise, 
tuolumnce.  and  tularensis  will  form  well  marked  subspecies  of  luna- 
longa, which  should  in  any  event  be  regarded  as  valid  with  reference 
to  pusilla. 

The  two  following  species  may  be  placed  near  denverensis  in  the 
pur  pur  ea  group: 

Cicindela  pugetana  n.  sp. — Fonm  rather  narrow  and  convex,  small 
in  size,  alutaceous,  bright  green  throughout  above  and  beneath,  the 
elytral  margins  brighter  green;  smoother,  less  punctate  and  with  a  feeble 
violaceous  reflection  by  oblique  illumination;  head  (cf )  densely  pubescent 
on  the  front  medially;  labrum  pale,  with  fine  black  anterior  edge,  the 
median  lobe  advanced  and  sharply  tridentate;  prothorax  much  narrower 
than  the  head,  slightly  transverse,  moderately  narrowed  basally,  uni- 
formly green  and  finely,  very  densely  sculptured;  elytra  two-thirds 
longer  than  wide,  not  quite  twice  as  wide  as  the  prothorax,  closely, 
granularly  punctate,  the  type  without  trace  of  humeral  spot  but  with  a 
very  minute  pale  spot  representing  the  posterior  end  of  a  humeral  lunule, 
also  with  an  externally  attenuated  triangular  spot  at  the  apex  and  with 
a  slender  elbowed  median  band,  not  attaining  the  sides;  terminal  ab- 
dominal sinus  broadly  parabolic;  sides  of  the  prosternum  with  long  con- 
spicuous pubescence,  the  remainder  of  the  under  surface  glabrous  or 
nearly  so;  legs  slender,  the  middle  tarsi  a  little  longer  than  the  tibiae.

evident  pubescence  of  the  under  surface  and  in  having  the  long 
white  coarse  hairs  along  the  external  sides  of  the  tibiae  very  dense 
and  conspicuous;  in  denverensis  there  are  only  very  sparse  erect 
white  bristles  along  the  tibiae. 

Cicindela  parallelonota  n.  sp. — Body  nearly  as  in  the  preceding, 
alutaceous  and  bright  green,  with  blue  reflection  by  oblique  light  through- 
out above,  more  shining  and  greenish-blue  beneath,  the  legs  metallic 
green;  head  (9  )  loosely  pubescent  throughout,  the  occiput  glabrous,  the 
frontal  convexity  more  densely  pubescent;  labrum  as  in  the  preceding 
but  with  the  median  lobe  rather  less  prominent,  though  even  more 
sharply  tridentate;  prothorax  shorter  and  broader,  transverse,  narrower 
than  the  head,  similarly  sculptured  and  with  deep  transverse  impressions; 
elytra  nearly  similar  in  form  and  proportion,  very  gradually  smoother, 
bluer  and  more  shining  toward  the  sides,  with  not  very  close-set  but 
sharply  granuliferous  moderate  punctures  uniformly  distributed  through- 
out, the  type  with  a  slender  but  complete  humeral  lunule,  a  broader 
complete  apical  lunule,  which  is  broadly  dilated  and  inflexed  anteriorly 
and,  at  the  middle  of  the  length  between  the  median  line  and  lateral 
sixth,  a  broad  transversely  parallelogramic  isolated  white  spot;  under 
surface  with  long  coarse  and  rather  sparse  white  hairs  laterally;  tibiae 
with  sparse  erect  white  hairs;  palpi  black  throughout.  Length  (9) 
1 1. 8  mm.;  width  4.7  mm.  Nevada  (Las  Vegas), — Spalding. 

The  three  species  denverensis,  pugetana  and  parallelonota,  form  a 
very  well  defined  group  of  the  genus,  not  very  closely  allied  to  any 
other  but  includable  within  the  limits  of  the  purpurea  group;  they 
are  all  distinctly  isolated  and  are  apparently  true  species.  Sierra 
Leng  also  seems  to  be  assignable  to  this  denverensis  group. 

I  have  recently  received  a  specimen  of  albertina  taken  by  Prof. 
L.  Bruner  at  Worland,  Wyoming.  It  does  not  differ  from  the 
Alberta  types.  It  is  quite  distinct  in  appearance  from  decemnotata. 

The  three  following  forms  belong  to  the  tranquebarica  group. 
I  will  describe  them  as  species,  for  they  are  all  distinctly  different 
from  any  heretofore  published,  but  will  designate  their  closest 
allies. 

Cicindela  wichitana  n.  sp. — Body  rather  small  in  size  and  of  stout 
abbreviated,  moderately  convex  form,  dull  in  lustre  and  dark  coppery- 
brown  to  obscure  green  throughout  above,  the  elytra  a  little  brighter 
greenish  or  coppery  laterally  and  the  bottoms  of  the  pronotal  sulci 
finely  blue;  under  surface  bluish-green,  the  prosternal  side-pieces  coppery; 
head  and  eyes  moderately  developed,  sparsely  pubescent,  densely  on  the 
frontal  umbo;  labrum  rather  short,  the  median  lobe  acutely  tridentate; 


22  MEMOIRS  ON  THE  COLEOPTERA 

prothorax  barely  (cf )  to  distinctly  (9  )  narrower  than  the  head,  a  third 
to  two-fifths  wider  than  long,  finely,  densely  sculptured;  elytra  marked 
throughout  nearly  as  in  tranquebarica,  with  the  punctures  rather  small 
and  not  close-set,  though  more  distinct  than  in  that  species,  more  ab- 
breviated in  form  and  with  the  fine  prolongation  of  the  humeral  lunule 
less  oblique;  legs  and  tarsi  more  slender;  tip  of  the  abdomen  (  9  )  differing 
in  being  canalicularly  impressed  apically.  Length  (cf  9  )  11.8-12.0  mm.; 
width  4.9-5.2  mm.  Kansas, — Knaus.  Four  specimens. 

This  may  prove  to  be  more  properly  a  subspecies  of  tranquebarica, 
but  it  differs  in  its  very  much  smaller  size  and  in  other  ways  as 
detailed  above. 

Cicindela  lassenica  n.  sp. — General  form  and  ornamentation 
nearly  as  in  tranquebarica  but  differing  remarkably  in  coloration,  deep 
black  throughout  above,  beneath  and  on  the  legs,  without  trace  of  metallic 
coloration  at  any  point,  very  dull  in  lustre  above,  rather  shining  beneath; 
head  (cf )  moderate,  with  long  sparse  hairs,  which  are  dense  on  the  frontal 
umbo;  labrum  rather  short,  tridentate  medially;  prothorax  large,  trans- 
versely quadrate,  fully  one-half  wider  than  long  and  as  wide  as  the  head, 
densely  sculptured;  elytra  oblong,  parallel,  with  less  arcuate  sides  than 
in  tranquebarica  but  with  identical  maculation,  the  middle  band  similar, 
the  posterior  arm  short  and  not  long  as  it  is  in  vibex  and  kirbyi;  punctures 
fine,  feeble,  close-set  and  strongly  granuliferous,  the  ground  very  opaque; 
under  surface  moderately  hairy  toward  the  sides,  coarsely  on  the  pro- 
pleura;  legs  moderate.  Length  (cf)  13.5  mm.;  width  5.3  mm.  Cali- 
fornia (without  further  indication  of  locality). 

Though  similar  to  tranquebarica  in  its  markings,  I  hardly  think 
that  the  taxonomic  value  of  this  form  can  be  less  than  specific. 

Cicindela  moapana  n.  sp. — Habitus  similar  to  that  of  r-ibex  and 
kirbyi  but  larger  and  with  more  elongate  and  larger  elytra,  dark  coppery- 
brown,  the  head  and  pronotum  a  little  brighter,  cupreous,  the  bottom  of 
the  deep  sulci  blue;  sides  of  the  elytra  smoother,  more  shining  and  rather 
bright  coppery-red;  under  surface  more  shining,  blue-green,  the  side- 
pieces  of  all  the  sterna  bright  coppery;  legs  cupreous-red;  head  (9  )  well 
developed,  with  sparse  white  hairs,  which  are  dense  on  the  frontal  umbo; 
labrum  short,  pale,  with  black  anterior  edge,  acutely  tridentate;  prothorax 
equal  in  width  to  the  head,  transverse,  slightly  narrowed  from  apex  to 
base,  sculptured  densely  as  usual;  elytra  large,  more  than  one-half 
longer  than  wide,  subparallel,  with  feebly  arcuate  sides  and  with  almost 
circularly  rounded  apex  in  posterior  third,  the  humeral  lunule  as  in  vibex, 
the  apical  as  in  kirbyi  but  much  broader,  the  median  band  unlike  any- 
thing else  in  the  group,  consisting  solely  of  the  posterior  arm  as  seen  in 
kirbyi,  the  portion  from  the  angle  to  the  sides  wholly  obsolete  and  without 
the  faintest  suggestion  caused  by  irregularity  of  sculpture,  the  latter 
being  perfectly  even  over  the  place  which  is  occupied  by  the  transverse 
part  of  the  band  in  the  allied  species;  legs  rather  long,  the  hind  tarsi  short, 
not  as  long  as  the  tibiae.  Length  (  9  )  15.0  mm.;  width  6.2  mm.  Nevada 
(McGill,  White  Pine  Co.,  6500  feet). 


OMUS    AND    ClCINDELA  23 

Either  this  and  the  preceding  should  be  regarded  as  distinct 
species  or  all  the  forms  in  the  true  tranquebarica  subgroup  should 
be  placed  as  subspecies  and  varieties  of  the  latter;  I  hold  strongly 
to  the  first  view. 

In  the  repanda  group  the  following  is  a  rather  well  marked  relative 
of  ancocisconensis: 

Cicindela  ancocisconensis  ssp.  dowiana  nov. — Similar  to  ancocisco- 
nensis in  general  facies  but  a  little  larger  and  more  elongate,  rather 
smoother  and  of  a  paler  brown  color;  prothorax  not  quite  so  transverse 
but  similarly  nearly  as  wide  as  the  head;  elytra  larger  and  longer,  the  fine 
punctures  much  less  close-set,  the  rather  fine  pale  maculation  similar, 
except  that  the  humeral  lunule  is  notably  longer;  tarsi  similarly  rather 
short.  Length  (9  )  14.0  mm.;  width  5.3  mm.  New  York  (De  Bruce),— 
R.  P.  Dow. 

This  form  can  be  distinguished  at  once  from  typical  ancocisconen- 
sis on  direct  comparison ;  my  series  of  the  latter  is  very  homogeneous 
and  is  from  North  Carolina  (Asheville)  and  Buffalo,  N.  Y. 

Having  now  at  hand  a  topotype  of  apicalis  of  the  togata  group, 
from  Kackley,  Ks.,  perfectly  matched  by  another  from  Lincoln, 
Neb.,  I  am  able  to  compare  the  three  described  forms  more  in- 
telligibly. Togata  and  apicalis  have  the  same  slender  outline,  but 
in  the  former  the  apical  elytral  spine  of  the  female  is  very  far 
retracted,  projecting  from  the  sutural  margin  far  from  the  tip;  in 
apicalis  this  spine  is  nearly  but  not  quite  at  the  apex  and  it  differs 
furthermore  from  togata,  in  having  the  short  projection  at  the 
position  of  the  median  band  more  acutely  angulate,  its  anterior 
slope  more  rectilinearly  oblique  and  the  reentrant  angle  behind  the 
humeral  part  more  acute.  In  globicollis  the  body  is  shorter,  the 
elytra  relatively  more  inflated  posteriorly  and  the  elytral  markings 
almost  exactly  as  in  togata,  but  the  elytral  spine  is  nearly  at  the 
apex  as  in  apicalis;  the  prothorax  differs  from  either  in  being  more 
inflated  at  the  median  part  of  the  sides.  It  is  probable  that  both 
apicalis  and  globicollis  should  be  considered  subspecies  of  togata, 
in  spite  of  the  markedly  different  position  of  the  apical  spine  of  the 
elytra  in  togata. 

The  following  is  a  distinct  species  of  the  togata  group: 

Cicindela  fascinans  n.  sp. — Nearly  similar  in  outline  to  globicollis, 
rather  bright  coppery-brown,  the  head  throughout  with  short  decumbent 
stout  white  hairs,  notably  close-set  and  even,  the  prothorax  with  slightly 
longer  and  less  close-set  Hairs  of  the  same  kind,  the  under  surface  green 


24  MEMOIRS  ON  THE  COLEOPTERA 

and  cupreous,  with  very  dense  white  hairs,  glabrous  only  along  the  middle, 
more  broadly  on  the  sterna;  eyes  large  and  prominent;  labrum  (cf) 
short,  with  a  single  small  acute  medial  tooth;  prothorax  much  narrower 
than  the  head,  nearly  as  long  as  wide,  convex,  parallel,  with  strongly 
and  evenly  rounded  sides;  elytra  subparallel,  acutely  ogival  at  tip,  white 
throughout,  except  a  cupreous  sutural  region  broad  at  base,  narrowly 
ending  at  two-thirds,  its  lateral  outlines  bilobate;  white  area  minutely 
and  sparsely,  the  cupreous  strongly  and  closely,  punctate;  serrulation  of 
the  apices  very  fine,  the  sutural  spine  strong  and  acute;  legs  very  slender, 
cupreous  and  green.  Length  (c?)  9.8  mm.;  width  3.4  mm.  New  Mexico 
(Santa  Rosa), — Knaus. 

This  is  a  very  interesting  form,  much  smaller  in  size  than  togata 
and  of  very  different  ornamentation. 

In  the  marginata  group,  amnicola  should  be  given  specific  rank 
and  mundula  attached  thereto  as  a  subspecies  or  variety. 

Cumatilis  and  collusor  are  merely  subspecies  of  rufiventris,  but 
hentzi  is  a  different  species,  allied  to  i6-punctata  and  sonorana  but 
distinct  from  either.  Beckeri  W.  Horn,  is  allied  to  sonorana  but  is 
smaller,  more  slender  and  much  more  brilliantly  cupreous  on  the 
head  and  prothorax;  I  have  in  my  collection  a  good  series  of  five 
examples  taken  by  Townsend  in  Chihuahua. 


II— SOME   OBSERVATIONS   ON   THE   CARABID^E 
INCLUDING  A   NEW  SUBFAMILY. 

A  few  more  or  less  interesting  new  Carabid  species  and  subspecies 
have  been  in  my  collection  for  some  time,  awaiting  a  convenient 
opportunity  for  publication.  It  would  be  better  to  have  had  them 
appear  in  the  course  of  systematic  work,  but  as  the  groups  to  which 
they  pertain  have  in  most  instances  been  studied  monographically 
in  comparatively  recent  times,  it  will  be  easy  to  make  the  necessary 
interpolations. 

Subfamily  CARABINE. 
Tribe  CYCHRINI. 

The  singularly  isolated  habitus  of  the  species  in  this  section  of 
the  Carabidse,  as  well  as  their  frequent  rich  metallic  coloring,  has 
caused  them  to  receive  a  large  amount  of  attention  from  collectors 
of  the  Coleoptera,  but  taxonomically  they  are  rather  difficult  to 
deal  with.  The  following  seem  to  be  some  rather  evident  novelties 
in  this  tribe: 

Irichroa  aeneicollis  ssp.  tricarinata  nov. — Form  nearly  as  in  cencicollis 
but  rather  narrower  and  more  elongate,  black,  without  metallic  reflection 
at  any  part,  except  a  very  feeble  greenish  glint  on  the  pronotum;  head 
and  antennae  nearly  similar;  prothorax  similar  in  form  and  size,  except 
that  the  sides  are  not  sharply  angulate  but  prominently  rounded,  the 
surface  more  rugulose  transversely,  the  longitudinal  impressions  a  little 
more  acutely  and  deeply  impressed  and  the  basal  margin  relatively 
narrower;  elytra  nearly  similar  but  rather  more  elongate  and  less  convex, 
the  striae  with  even  coarser  and  more  crowded  punctures  and  with  inter- 
vals 4-8-12  elevated,  becoming  feebly  cariniform  basally;  tarsi  nearly 
similar.  Length  (cf)  18.5  mm.;  width  7.7.  mm.  North  Carolina  (Blue 
Ridge  Mts.), — Beutenmiiller. 

The  geographical  habitat  is  different  from  that  of  (eneicollis, 
which  has  occurred  so  far  only  on  the  Black  and  Balsam  Mts.  of 
North  Carolina  and  Tennessee;  it  is  a  distinct  species  and  by  no 
means  a  subspecies  or  variety  of  andrewsi. 

Sphaeroderus  lecontei  ssp.  diffractus  nov. — -Similar  in  general  form 
and  habitus  to  lecontei  but  more  slender  and  very  much  smaller,  shining, 

25

black,  with  violet  lustre,  the  elytra  obscure  cupreous;  under  surface  and 
legs  deep  black;  head  as  in  lecontei,  the  antennae  relatively  distinctly 
shorter,  slender;  prothorax  as  in  lecontei  throughout  but  with  the  sides 
more  prominently  rounded  medially,  the  base  similarly  bi-impressed  and 
sparsely  punctured  between  the  foveae;  elytra  nearly  similar  but  narrower, 
the  strial  punctures  less  distinct  and  all  the  intervals  irregularly  broken 
up  and  tuberculiferous  apically  and  in  about  lateral  third,  except  basally; 
anterior  tarsi  (cf )  less  strongly  dilated,  the  first  joint  rather  longer  than 
wide.  Length  (d71)  10.0  mm.;  width  4.6  mm.  New  Brunswick. 

The  head  and  prothorax  are  relatively  a  little  smaller  than  in 
lecontei  and  the  hind  tarsi  still  shorter,  the  anterior  tarsi  of  the 
male  are  much  less  dilated  and  the  elytral  sculpture  more  confused 
laterally. 

Brennus  Mots. 

This  group  of  the  Cychrini,  whether  wholly  valid  as  a  genus  or 
not,  is  at  any  rate  very  definitely  circumscribed.  The  conditions 
prevai  ing  within  it  are  similar  to  those  pertaining  to  Omus  and 
Euschides;  that  is  to  say,  we  see  a  geologically  recent  type  splitting 
into  a  most  confusing  variety  of  subordinate  forms,  due  principally 
to  geographic  isolation  in  mountainous  country,  but  at  the  present 
stage  of  development  exhibiting  a  process  of  segregation  nto  a 
more  limited  number  of  tolerably  definite  primary  or  stem  forms, 
with  many  allied  subordinates  in  each  case.  I  have  no  doubt  at 
all  that  these  satellites  of  the  more  definite  stem  forms  should  be 
called  subspecies,  but  to  go  further  and  discriminate  such  categories 
as  varieties,  aberrations  and  monstrosities,  is  wholly  unwarranted 
at  the  present  stage  of  knowledge.  It  is  also  a  very  difficult  matter 
to  decide,  with  our  present  lights,  just  which  should  be  considered 
stem  forms  and  thus  receive  the  designation  of  species,  and  which 
should  continue  as  subspecies.  That  Dr.  Roeschke  has  carried 
the  lumping  too  far  is  I  think  self-evident.  For  example,  under 
ventricosus  he  places  both  striatus  Lee.  and  fuchsianus  Riv.,  in  sub- 
ordinate rank;  this  is  clearly  unwarranted,  for  they  both  differ 
profoundly  from  ventricosus  Dej.,  in  general  habitus  and  other 
characters  of  moment  in  this  genus.  The  author  has  also,  quite 
without  any  sort  of  warrant,  suppressed  my  symmetricus  as  a 
monstrosity,  but  for  what  reason  is  unknown;  it  is  altogether  iso- 
lated in  general  habitus  and  gives  no  indication  of  being  an  aberra- 
tion in  the  usual  meaning  of  that  word;  but  only  the  single  char- 


CARABID/E  27 

acteristic  of  sculpture  was  considered  by  him.  Again,  without  any 
kind  of  justification,  he  has  relegated  to  inferior  rank  compositus, 
por catus  and  insularis  Csy.,  on  pure  assumption;  his  views  in  regard 
to  these  four  species  are  certainly  erroneous.  The  finely  reflexed, 
completely  non-metallic  elytral  margins  and  the  general  facies  of 
porcatus  are  more  nearly  as  in  the  obliquus  series,  although  the 
supra-orbital  seta  shows  that  it  must  be  associated  with  dissolutus. 
Dissolutus,  it  seems,  was  not  represented  in  my  collection  when  I 
drew  up  my  revision  of  Brennus,  but  I  have  since  received  a  speci- 
men taken  by  Dr.  Blaisdell  at  Mokelumne  Hill,  Calaveras  Co.; 
it  is  closely  allied  to  interruptus;  the  elytra  are  more  shining  and 
the  elytral  margins  moderately  metallic  and  more  broadly  reflexed 
than  in  porcatus;  the  female  of  the  latter  is  also  now  at  hand,  from 
the  same  source  as  the  male  type;  I  had  confused  it  with  the  female 
of  opacicollis,  they  are  mutually  so  very  similar.  The  forms 
allied  to  interruptus  and  dissolutus  are  in  a  condition  of  decided 
incertitude  and  confusion.  The  author  has  given  very  little 
attention  to  points  that  must  be  of  considerable  taxonomic  value, 
such  as  the  number  of  elytral  striae,  metallic  or  non-metallic  elytral 
margins  and  structure  of  the  anterior  male  tarsi  and  his  separation 
of  the  oreophilus  section  because  of  a  feeble  incurvature  of  the 
thoracic  base,  is  a  rather  weak  feature;  this  feeble  sinuosity  exists 
also  in  productus  described  below. 

In  regard  to  my  previous  work  in  this  genus,  which  is  so  severely 
condemned  by  Dn  Roeschke,*  I  have  only  to  say  that  conditions 
were  such  at  that  time  that  I  could  not  consult  all  the  original 
literature  and  had  to  rely  upon  the  identifications  of  my  prede- 
cessors, so  far  as  possible.  It  is  for  this  reason  that  I  failed  to 

*  The  generally  undisguised  animus  toward  me  and  my  work,  exhibited  by  Dr.  Hans 
Roeschke  in  the  course  of  his  Monograph  on  the  Cychrini,  is  quite  unaccountable, 
for  such  a  personal  attitude  was  entirely  unnecessary  in  a  critical  review.  The  intima- 
tion made  on  page  102,  with  the  most  amusing  naivete,  that  my  "Arten"  have  in 
every  instance  proven  to  be  spurious  or  to  be  masquerading  under  false  pretenses, 
will  be  in  considerable  part  controverted  under  more  reasonable  and  unbiased  com- 
parative study  from  the  types.  It  would  have  been  at  least  in  better  taste  had  the 
author  given  the  benefit  of  the  doubt  to  his  fellow  worker,  in  those  cases  where  he  could 
not  be  sure,  because  of  lack  of  authentic  material.  As  a  matter  of  fact  neither  Dr. 
Roeschke  nor  his  active  helper  in  this  country,  Dr.  Van  Dyke,  has  ever  written  me  a 
line  concerning  my  collection  or  has  ever  had  so  much  as  a  glimpse  of  any  of  my  types 
or  evinced  any  desire  whatever  to  see  them.  His  work  contains  many  errors  of  identi- 
fication, which  I  hope  it  may  be  my  pleasure  to  demonstrate  to  him  eventually. 


28  MEMOIRS  ON  THE  COLEOPTERA 

identify  ventricosus  (sinuatus  Csy.),  interruptus  and  dissolutus 
properly,  but  from  what  I  can  glean  from  the  Roeschke  mono- 
graph, my  identification  of  ventricosus  was  the  large  form  called 
by  him  lativentris  Mots. ;  it  was  in  no  sense  the  fuchsianus  of  Rivers, 
as  stated  by  the  author.  My  identification  of  striatopunctatus  Chd., 
was  the  form  which  the  author  calls  alternatus  Mots.  My  deter- 
mination of  ovalis  Mots,  is  correct,  as  it  agrees  thoroughly  with  the 
description  and  particularly  with  the  careful  figure  given  by  Mot- 
schulsky.  Gentilis  Csy.,  is  a  valid  subspecies  at  least;  it  has  smaller 
punctures  than  crenatus  Mots.,  and  is  stouter  in  form  in  both 
sexes.  Opacicollis,  convergens  and  sculptipennis  are  distinct  among 
themselves  and  are  not  all  varieties  of  obliqims.  Basalis  is  a  valid 
species  and  duplicatus  is  rather  more  than  a  subspecies  of  cristatus. 
One  source  of  trouble  is  that  Dr.  Roeschke  does  not  know  my  work 
very  thoroughly,  because  of  frequent  failure  to  grasp  my  meaning, 
probably  largely  because  of  unfamiliarity  with  the  English  language; 
the  consequence  is  that  he  has  failed  to  identify  my  species  cor- 
rectly. Another  origin  of  discord  is  the  fact  that  we  evidently 
have  radically  different  ideas  as  to  the  meaning  of  the  word  species; 
this  is  a  matter  of  opinion,  the  correctness  of  which  need  not  greatly 
concern  us,  as  it  will  be  definitely  adjudicated  under  the  light  of 
future  knowledge ;  the  question  now  is  more  essentially  one  regarding 
absolute  synonymy,  but  in  the  Roeschkean  sense,  a  synonym  need 
not  necessarily  be  a  synonym. 

The  following  are  some  additional  forms  in  this  genus: 

Brennus  rugiceps  ssp.  congener  nov. — Body  moderately  ventricose 
and  convex,  deep  black,  shining,  the  pronotum  opaculate;  head  in  almost 
every  way  as  in  incipiens,  the  irregular  crest  having  an  elongate  crater- 
like  posterior  excavation,  partially  closed  posteriorly  by  a  short  longi- 
tudinal ridge;  prothorax  differing  decidedly,  smoother  and  more  opaque, 
slightly  elongate,  the  sides  subangularly  widest  before  the  middle, 
thence  oblique  and  straight  to  the  subbasal  sinus,  thence  subparallel  and 
straight  for  a  considerable  distance  to  the  basal  margin,  which  is  trans- 
verse to  feebly  sinuato-truncate  and  half  the  maximum  width  (9), 
much  less  (cT);  elytra  less  than  one-half  longer  than  wide,  oval,  rather 
transversely  rounded  at  base,  deeply  but  very  irregularly  i8-striate, 
the  striae  moderately  broken  but  easily  traceable  throughout  at  the 
sides,  rather  finely  and  indistinctly  punctate,  the  intervals  moderately 
convex,  strongly  so  laterally;  margins  finely  re  flexed,  not  metallic; 
anterior  tarsi  (cf)  with  the  first  joint  in  apical  third,  the  second  and  third 
wholly  spongy-pubescent  beneath,  the  fourth  without  trace  of  squamules. 
Length  (o71  9  )  12.5-14.5  mm.;  width  5.8-6.7  mm.  Oregon  (Josephine 
Co.), — Nunenmacher.  A  single  pair. 


CARABINE  29 

Differs  from  incipiens  in  the  angulate  sides  of  the  prothorax, 
these  being  strongly  but  evenly  rounded  at  the  point  of  greatest 
width  in  incipiens,  and  in  the  latter  the  sides  toward  base  are  still 
converging,  not  subparallel  as  in  congener;  the  pronotum  is  more 
shining  and  more  coarsely  rugulose  in  incipiens.  Both  of  these 
forms  are  possibly  subspecies  of  rugiceps. 

Brennus  productus  n.  sp. — Elongate,  ventricose,  only  very  moder- 
ately convex,  black,  alutaceous  throughout,  the  elytra  rather  more  shining; 
head  as  in  ventricosus  but  much  narrower,  the  labral  lobes  similar  but 
less  diverging;  supra-orbital  puncture  feeble  but  evident;  prothorax 
differing  greatly,  being  small  and  narrow,  more  nearly  as  in  striatus, 
fully  as  long  as  wide  but  apparently  somewhat  elongate,  the  sides  an- 
teriorly inflated  and  broadly  rounded,  thence  oblique  posteriorly,  then 
sinuate,  becoming  straight  and  parallel  for  an  unusually  long  distance 
before  the  base,  this  being  fully  a  fifth  the  total  length;  sides  strongly 
re  flexed  but  not  so  strongly  as  in  ventricosus;  surface  nearly  as  in  the 
latter;  base  narrower  and  broadly  sinuate  as  in  oreophilus,  one-half  the 
maximum  width;  elytra  evenly  elliptic,  one-half  longer  than  wide,  finely 
but  deeply  about  ij-striate,  the  striae  very  regular  and  with  rather  small 
punctures,  becoming  coarser  laterally,  the  striae  outside  the  thirteenth 
much  confused  and  barely  traceable;  intervals  convex;  margins  strongly 
reflexed,  not  metallic;  anterior  tarsi  (cf)  nearly  as  in  the  preceding 
throughout.  Length  (cf )  15.7  mm.;  width  7.0  mm.  California  (exact 
locality  unrecorded  but  probably  coastal). 

The  general  appearance  of  this  species  is  unlike  any  other  known 
to  me  but  seems  to  approach  striatus  more  closely  than  ventricosus; 
the  probabilities  are  that  it  will  prove  to  be  of  specific  rather  than 
subspecific  value  and  it  is  therefore  so  announced. 

Brennus  integer  n.  sp.— Body  small  in  size,  strongly  ventricose,  very 
shining  and  deep  black  throughout,  the  reflexed  margins  of  the  elytra 
violaceous;  head  moderate,  smooth  and  shining  along  the  middle,  with  a 
supra-orbital  seta;  antennae  slender,  about  as  long  as  the  elytra;  prothorax 
relatively  small,  rather  wider  than  long,  the  sides  inflated  and  evenly 
rounded  anteriorly,  rapidly  very  oblique  posteriorly,  abruptly  sinuate 
near  the  base,  the  sides  thence  parallel  and  straight  to  the  base,  which  is 
transverse  and  distinctly  less  than  half  the  maximum  width;  surface 
shining,  finely  subrugulose,  feebly  impressed  along  the  sides,  the  trans- 
verse impressions  and  median  stria  strong,  the  margin  strongly  reflexed; 
elytra  oval,  obliquely  attenuate  and  sharply  pointed  posteriorly,  very 
convex,  with  fourteen  deeply  impressed  striae,  complete  and  perfectly 
regular  throughout  the  width,  not  at  all  confused  laterally,  the  punctures 
not  large  and  but  slightly  crenulating  the  very  convex  and  perfectly  even 
intervals  throughout,  the  latter  very  highly  polished;  male  with  the 
anterior  tarsi  rather  feebly  dilated;  joints  two  and  three  and  less  than 
apical  third  of  the  first  densely  spongiose  beneath.  Length  (cf)  12.4 
mm.;  width  5.8  mm.  California  (Sta.  Cruz).

This  species  is  about  the  smallest  of  the  interrupt  us  series  and 
may  be  placed  near  corpulentus,  which  however  has  about  fifteen 
striae,  irregular  laterally  and  without  trace  of  metallic  margin. 

Brennus  oreophilus  ssp.  humeralis  nov. — Smoother  and  more  ven- 
tricose  than  oreophilus,  shining,  the  pronotum  similarly  smooth  and 
opaculate;  head  nearly  similar;  prothorax  relatively  somewhat  smaller 
and  narrower,  fully  as  long  as  wide  and  apparently  a  little  longer,  the 
anterior  angles  more  rounded,  the  sides  posteriorly  similarly  oblique  and 
feebly  sinuate;  base  slightly  sinuate  and  one-half  the  maximum  width; 
surface  and  margins  nearly  as  in  oreophilus;  elytra  differing  decidedly, 
more  inflated,  barely  a  third  longer  than  wide,  the  sides  rapidly  rounding 
inward  at  base  to  the  thoracic  base,  the  humeri  thus  more  evident  than 
in  any  other  form  of  the  genus,  the  apex  acutely  ogival;  surface  very 
convex,  rather  finely  striate,  the  striae  finely,  not  closely  punctate,  very 
much  finer  and  more  finely  punctate  than  in  oreophilus,  confused  in  nearly 
lateral  third;  male  with  the  anterior  tarsi  distinctly  dilated;  joints  two 
and  three  and  apical  half  of  the  first  densely  spongy-pubescent,  the  fourth 
without  squamules.  Length  (cT )  15.0  mm.;  width  7.0  mm.  California 
(Mokelumne  Hill,  Calaveras  Co.), — Blaisdell. 

In  the  male  of  oreophilus  the  anterior  tarsi  are  rather  less  dilated 
but  similarly  clothed  beneath,  except  that  the  first  joint  is  densely 
clothed  in  rather  less  than  apical  half;  the  elytra  are  more  evenly 
rounded  at  the  sides  basally  and  the  elytral  striae,  and  especially 
the  punctures,  are  much  coarser.  From  hoppingi  Roe.,  in  which 
also  the  humeri  are  somewhat  more  evident  than  in  oreophilus, 
humeralis  may  be  known  at  once  by  the  much  shorter,  more  finely 
punctate  and  more  shining  elytra,  more  distinct  humeri  and  less 
sinuate  oblique  sides  of  the  prothorax. 

The  Sierra  form  placed  with  lativentris  Mots.,  by  Dr.  Roeschke 
is  not  exactly  the  same,  the  general  habitus  is  very  similar  but  the 
prothorax  is  somewhat  shorter  and  broader. 

Maronetus  n.  gen. 

In  describing  Pseudonomaretus,  Dr.  Roeschke  failed  to  indicate 
any  type  species  and,  as  he  included  two  distinct  genera  under  that 
name,  I  will  here  designate  the  large  and  conspicuous  and  more 
completely  striate  species  relictus  Horn  as  the  type;  regularis  Lee., 
merkeli  Horn  and  idahoensis  Webb,  will  also  form  part  of  Pseudo- 
nomaretus and  perhaps  one  or  two  other  similar  forms.  Under  the 
name  Maronetus,  I  have  separated  the  smaller  and  more  slender 
species,  with  less  complete  elytral  striation,  of  which  the  following 
may  be  regarded  as  the  type. 


CARABID.E  31 

Maronetus  tenuis  n.  sp. — Form  slender,  very  convex  and  shining, 
somewhat  piceous-black,  the  legs  piceous;  head  scarcely  two-thirds  as 
wide  as  the  prothorax,  the  eyes  moderate;  labral  lobes  very  slender,  the 
notch  almost  attaining  the  base;  front  smooth;  supra-antennal  edge 
strongly  elevated;  antennae  slender,  testaceous,  not  quite  two-thirds  as 
long  as  the  body,  the  basal  joint  not  quite  as  long  as  the  next  three  com- 
bined; prothorax  narrow,  longer  than  wide,  the  sides  inflated  and  evenly 
rounded  anteriorly,  oblique  and  straight  thence  to  the  base,  which  is 
feebly  sinuate  medially,  two-thirds  the  maximum  width  and  slightly 
wider  than  the  apex,  the  latter  truncate,  with  obtuse  and  broadly  rounded 
angles;  surface  smooth,  the  transverse  impressions  rather  sharply  marked, 
the  stria  connecting  them  along  the  middle  distinct,  the  basal  foveae 
deep,  short,  impunctate,  separated  from  the  margin  by  a  thin  cariniform 
wall;  lateral  edges  without  trace  of  reflexed  margin;  elytra  elongate-oval, 
three-fourths  longer  than  wide,  less  than  twice  as  wide  as  the  prothorax, 
the  sutural  stria  coarse,  deep,  coarsely  punctate,  extending  from  near 
the  base  to  apical  third,  the  second  stria  much  less  coarse  and  more 
finely  punctate,  extending  less  closely  to  the  base  and  obsolete  behind 
the  middle,  the  third  stria  represented  only  by  a  very  fine  feeble  im- 
punctate impressed  line,  very  short  and  only  visible  by  very  oblique 
illumination;  all  the  other  striae  completely  obsolete,  the  surface  very 
smooth  and  polished;  the  fine  marginal  stria  is  visible  feebly  near  the 
apex;  reflexed  margin  extremely  fine;  legs  slender,  the  hind  tarsi  rather 
short,  slender.  Length  (9)  6.8  mm.;  width  2.1  mm.  North  Carolina 
(Black  Mts.), — Beutenmuller. 

This  remarkable  species,  the  smallest  of  our  Cychrini,  may  be 
distinguished  at  once  from  imperfectus  Horn,  with  which  it  has  been 
confounded,  by  the  complete  absence  of  any  trace  of  a  reflexed 
lateral  thoracic  margin,  by  having  only  two  elytral  striae  and  by 
its  smaller  size  and  more  slender  form.  In  imperfectus  the  pro- 
thorax  is  much  less  narrow  than  in  tenuis  and  there  is  a  distinct  and 
entire  though  rather  feebly  developed  reflexed  thoracic  margin. 
The  setigerous  puncture  at  two-fifths  from  the  apex — the  point  of 
maximum  width — is  as  well  developed  as  usual;  the  subbasal  punc- 
ture and  seta  are  rather  small  but  distinct.  This  genus,  besides 
tenuis  and  imperfectus,  will  comprise  a  number  of  other  species 
such  as  hubbardi  and  incompletus  Schwarz  and  schwarzi  Beuten- 
muller. 

Tribe  CARABINI. 
Calosoma  Weber. 

I  have  recently  received  from  Mr.  Knaus  three  specimens  in 
this  genus  that  are  of  peculiar  interest.  One  of  them  is  the  true 
prominens,  of  LeConte,  taken  at  Phoenix,  Ariz.,  and  hitherto  not

represented  in  my  collection;  it  is  obviously  widely  different  from 
peregrinator.  Another  is  an  example  of  carbonata  Lee.,  from  Oak 
Creek,  Ariz.,  its  most  western  limit  of  range  known  to  me.  Ingens 
Csy.,  is,  I  think,  a  distinct  species  and  not  a  subspecies;  it  has  a 
much  shorter  and  relatively  broader  hind  body  than  in  peregrinator 
or  carbonata  and  is  of  very  much  larger  size  than  amplipennis.  All 
of  these  species  and  subspecies,  together  with  apacheana  Csy., 
form  a  group  distinguished  by  the  rather  large  head,  long  antennae, 
more  or  less  feebly  angulated  sides  of  the  prothorax  and  feeble 
elycral  sculpture.  The  third  specimen  represents  an  undescribed 
species,  which  may  be  known  as  follows: 

Calosoma  Clemens  n.  sp. — Size  very  much  smaller  and  more  slender, 
deep  black,  rather  shining;  head  and  prothorax  relatively  much  smaller 
than  in  the  peregrinator  group,  the  former  with  very  prominent  eyes; 
vertex  sparsely  but  rather  coarsely  punctate;  mandibles  with  the  incurved 
apex  very  acute,  strongly,  transversely  rugose  throughout  above;  an- 
tennae slender,  shorter  than  in  peregrinator,  extending  to]  basal  fifth  or 
sixth  of  the  elytra,  the  third  joint  as  long  as  the  next  two;  prothorax 
three-fourths  wider  than  long,  conspicuously  small  in  size,  the  sides 
obtusely  angulate  at  the  middle,  strongly  rounded  anteriorly,  oblique 
and  nearly  straight  posteriorly;  base  feebly  sinuate  at  each  side,  the 
posteriorly  produced  angles  small  and  acute,  somewhat  everted  at  tip; 
surface  feebly  convex,  very  finely  punctulate  and  confusedly  creased, 
moderately  and  rather  sparsely  punctured  along  the  sides  and  apex  and 
more  coarsely  punctured  and  rugose  along  the  base;  latero-basal  im- 
pressions rather  narrow  and  deep;  sides  somewhat  broadly  and  feebly 
concavo-deplanate,  the  edge  very  moderately  re  flexed ;  elytra  nearly  three- 
fourths  longer  than  wide,  almost  twice  as  wide  as  the  prothorax,  very 
slightly  wider  at  apical  fourth  than  at  base,  the  sides  very  feebly  arcu- 
ate, the  apex  obtusely  ogival;  surface  with  fine  striae  of  minute  punctures, 
connected  by  transverse  and  rather  deep  coarse  lines  basally  and  laterally, 
the  foveae  very  minute;  lateral  margins  somewhat  broadly  re  flexed  and 
just  visibly  metallic  steel-bluish;  legs  slender,  rather  short,  the  hind  tarsi 
three-fourths  as  long  as  the  tibiae;  anterior  tarsi  (cf )  as  in  peregrinator 
but  rather  less  dilated.  Length  (of1)  20.0  mm.;  width  8.2  mm.  Nevada 
(Las  Vegas), — -Spalding. 

This  species  belongs  to  the  prorninens,  parvicollis,  subgracilis 
section  of  the  genus,  which  is  well  distinguished  from  the  pere- 
grinator section  by  the  smaller  head;  the  sides  of  the  elytra  basally 
are  feebly  serrulate  in  both  these  sections,  but  in  lugubris,  with 
which  peregrinator  is  compared  by  Bates,  these  serrulations  are 
obsolete;  the  prorninens  referred  to  by  Bates  at  the  same  place  in 
the  "Biologia,"  is  undoubtedly  parvicollis  Fall  and  not  the  true 


CARABID.E  33 

prominent  Lee.  Subgracilis  was  when  described  represented  by 
the  male  alone,  the  female  also  is  now  at  hand;  it  agrees  thoroughly 
with  the  male  in  general  form  and  habitus  but  is  much  larger; 
it  is  a  narrower,  more  elongate  and  polished  species  than  pere- 
grinator  and  has  a  distinctly  smaller  head,  showing  that  it  belongs 
with  the  prominens  series. 

Calosoma  semilaevis  ssp.  davidsoni  nov. — General  habitus,  lustre 
and  sculpture  as  in  semilcevis  but  more  elongate,  with  the  prothorax 
much  smaller,  less  transverse  and  having  the  parallel  sides  much  less 
rounded;  elytra  a  little  smoother  and  more  shining.  Length  (cf  9  ) 
21.0-24.0  mm.;  width  9.4-10.5  mm.  California  (Alameda  Co.). 

This  is  the  variety  alluded  to  in  my  previous  article  on  Calosoma 
(Mem.  Col.  IV,  p.  65) ;  its  appearance  is  very  distinct  from  that  of 
semilcEvis  and  it  should  be  designated  by  name ;  it  is  named  in  honor 
of  Dr.  George  Davidson.  Semilcevis  is  common  near  San  Francisco; 
there  is  one  example  in  my  series  which  does  not  seem  to  differ, 
marked  Guadalupe  Island. 

Subfamily  PTEROSTICHIN^E. 
Adrimus  Bates. 

The  following  species  seems  certainly  to  belong  to  this  genus, 
which  is  disseminated  in  very  moderate  number  from  the  Amazon 
regions  to  Mexico: 

*Adrimus  panamensis  n.  sp. — Moderately  stout  and  convex,  strongly 
shining  throughout,  the  elytra  with  evident  iridescent  lustre,  piceous- 
black  in  color,  rather  paler  beneath,  the  legs  throughout  and  the  palpi 
pale  flavo-testaceous;  head  smooth,  nearly  three-fourths  as  wide  as  the 
prothorax,  with  large  and  prominent  eyes,  the  foveae  impressed  and 
oblique,  the  palpi  very  slender;  antennae  slender  and  filiform,  rather 
more  than  half  as  long  as  the  body,  feebly  infuscate,  clearer  testaceous 
basally;  prothorax  about  a  third  wider  than  long,  widest  before  the 
middle,  the  sides  broadly,  evenly  rounded,  slightly  converging  basally, 
becoming  feebly  sinuate  at  the  hind  angles,  which  are  finely  acute  and 
prominent;  base  transverse,  beaded  only  laterally,  a  little  wider  than  the 
apex,  which  is  moderately  sinuate,  with  rather  distinct  angles;  surface 
smooth,  finely  reflexed  at  the  sides,  without  trace  of  transverse  impressions 
and  extremely  minutely,  sparsely  and  feebly  punctulate  throughout  at 
base,  the  stria  very  fine,  not  entire,  the  foveae  elongate,  narrow,  linear 
and  moderately  impressed;  elytra  barely  two-fifths  longer  than  wide 
and  about  one-half  wider  than  the  prothorax,  parallel,  with  rather  arcuate 
sides  and  rapidly  ogival  apex,  the  sinus  feeble,  the  fold  evident;  striae 
fine  but  rather  deeply  impressed,  finely,  closely  and  very  evenly  punctate,

34  MEMOIRS  ON  THE  COLEOPTERA 

the  punctures  gradually  obsolescent  apically,  the  scutellar  stria  completely 
wanting,  the  fovea  distinct;  intervals  moderately  convex,  the  third  with  a 
substrial  puncture  just  behind  basal  third;  lateral  line  of  foveae  not 
interrupted;  hind  tarsi  slender,  filiform,  the  basal  joint  about  as  long  as 
the  next  two  and  a  little  longer  than  the  fifth;  anterior  tarsi  (d")  moder- 
ately dilated,  biseriately  and  closely  squamulose  beneath,  the  middle 
tarsi  very  slender  and  unmodified.  Length  (cf)  6.0  mm.;  width  2.15 
mm.  Isthmus  of  Panama  (Colon),  —  Beaumont. 

To  be  readily  known  from  olivaceus  Bates,  from  Guatemala, 
by  its  smaller  size  and,  though  nearly  similar  in  outline  to  that 
species  as  figured,  it  seems  to  differ  so  radically  in  its  obsolete 
anterior  thoracic  impression,  feebler  foveae,  very  much  finer  basal 
punctures  and  not  at  all  explanate  basal  angles,  that  a  different 
though  closely  related  genus  may  be  indicated.  The  sides  of  the 
prothorax  have  a  seta  behind  apical  third  and  another  smaller 
at  the  hind  angles. 


Subfamily 

Chlaenius  Bon. 

The  following  forms,  some  specific  and  some  which  may  be 
regarded  at  present  as  of  subordinate  value,  may  be  conveniently 
defined  at  the  present  opportunity: 

Chlaenius  regularis  ssp.  apacheanus  nov.  —  Form  and  facies  somewhat 
as  in  regularis  Lee.,  feebly  shining,  the  elytra  opaculate;  upper  surface 
deep  indigo-blue  throughout,  the  under  surface  black,  the  legs  rufous; 
head  as  in  regularis,  the  antennae  similar  but  rather  shorter;  prothorax 
shorter,  transverse,  fully  two-fifths  wider  than  long,  otherwise  as  in 
regularis  throughout;  elytra  in  form,  sculpture  and  relationship  with  the 
prothorax  nearly  similar  but  more  abbreviated;  under  surface  nearly 
similarly  but  rather  less  densely  punctured  and  pubescent;  male  with  the 
anterior  tarsi  distinctly  shorter,  the  punctures  on  the  upper  surface  of 
the  three  dilated  joints  coarser,  the  second  joint  distinctly  wider  than 
long,  the  third  but  very  little  longer  than  wide.  Length  (cf  9  )  13.0- 
13.5  mm.;  width  5.5-6.0  mm.  Arizona  (southwestern)  and  the  adjacent 
parts  of  California.  Five  examples. 

Closely  allied  to  regularis  Lee.,  which  is  not  a  variety  of  sericeus, 
but  differing  in  its  smaller  size,  shorter  prothorax  and  shorter  and 
more  punctate  anterior  male  tarsi;  in  regularis,  the  dilated  joints 
of  the  anterior  male  tarsi  are  feebly  punctate  on  their  upper  surface, 
the  second  is  quadrate  and  the  third  much  longer  than  wide. 
It  differs  from  viridifrons  in  its  stouter  form  and  entirely  violet- 
blue  upper  surface. 


CARABID^;  35 

Comparing  a  male  of  sericeus  from  New  York  with  a  male  of 
perviridis  Lee.,  from  Siskiyou  Co.,  California,  a  number  of  rather 
radical  differences  become  apparent;  the  size,  for  example,  of 
perviridis  is  smaller  and  the  form  more  slender;  the  maxillary  palpi, 
legs  and  tarsi  are  relatively  shorter;  if  not  specifically  different, 
which  I  hold  to  be  the  case,  perviridis  is  therefore,  at  any  rate,  a 
well  defined  subspecies  of  sericeus.  The  following  is  apparently 
another  : 

Chlaenius  sericeus  ssp.  uteanus  nov. — Form  narrower  and  more 
elongate  than  in  sericeus,  the  elytra  smoother;  upper  surface  green, 
changing  to  violet  by  very  oblique  illumination,  shining  anteriorly,  the 
elytra  opaculate;  head,  antennae  and  palpi  as  in  perviridis,  the  antennae, 
as  well  as  the  palpi,  shorter  than  in  sericeus;  prothorax  differing  from  either, 
being  narrower  and  more  elongate,  nearly  as  long  as  wide,  otherwise 
similar,  except  that  the  punctures  are  not  quite  so  coarse  or  close-set; 
elytra  differing  from  both  in  being  more  oblong  and  rectilinearly  parallel 
and  in  having  the  striae  still  finer  and  not  in  the  least  impressed  even 
basally,  the  punctures  basally  not  more  evident  as  they  are  in  both 
sericeus  and  perviridis;  angle  made  by  the  basal  and  marginal  beads  more 
acute  than  in  either;  under  surface  less  closely  or  coarsely  punctured  than 
in  perviridis;  anterior  tarsi  (cf)  with  the  first  three  joints  diminishing 
less  rapidly  in  width  than  in  perviridis.  Length  (cf)  14.0  mm.;  width 
6.0  mm.  Utah  (Provo), — YVickham. 

The  type  of  this  subspecies  undoubtedly  presents  a  different 
appearance  from  the  male  of  either  sericeus  or  perviridis,  but  at 
the  same  time,  I  have  two  examples  that  were  also  taken  at  Provo 
by  Wickham,  that  have  a  shorter  prothorax  and  brighter  green 
color,  though  similar  otherwise,  and  I  regard  them  as  identical 
with  uteanus;  they  differ  in  facies  from  perviridis,  because  of  the 
more  oblong  and  less  oval  elytra.  My  series  of  the  true  sericeus 
extends  in  locality  from  Rhode  Island  to  Lake  Superior  and  Arizona 
and  displays  no  very  noticeable  variability. 

The  large  series  at  hand  show  quite  conclusively  that  leucoscelis 
Chev.,  and  cordicollis  Kirby  are  distinct  species;  the  former  is 
somewhat  smaller  in  size  and  very  much  more  slender  in  build, 
of  a  deeper  indigo-blue  color  and  differs  in  numerous  other  minor 
characters.  The  following  are  well  defined  species  allied  to  leuco- 
scelis and  cordicollis  respectively: 

Chlaenius  gilensis  n.  sp. — Body  much  smaller  than  in  lencoscelis, 
the  elytra  more  parallel  and  more  abbreviated;  head  nearly  similar,  the 
eyes  still  larger  and  more  prominent;  antennae  and  palpi  longer  and  more 


36  MEMOIRS  ON  THE  COLEOPTERA 

slender;  prothorax  similar  and  dark  steel-blue  but  with  more  numerous 
punctures  anteriorly,  basally  and  toward  the  median  stria;  elytra  differing 
greatly  in  form;  being  parallel,  with  just  visibly  arcuate  sides  and  only 
about  one-half  longer  than  wide,  deep  steel-blue,  striate  and  punctured 
as  in  leucoscelis  but  with  the  interstitial  punctures  finer;  broadly  rounded 
reflexed  edge  at  the  humeri,  the  under  surface  and  legs  nearly  similar. 
Length  (cf  9  )  12.0  mm.;  width  4.9-5.0  mm.  Arizona  (Yuma).  A 
single  pair  taken  by  the  writer. 

In  leucoscelis  the  elytra  are  much  longer  and  are  gradually  slightly 
inflated  posteriorly,  being  widest  behind  the  middle  and  with 
notably  arcuate  sides;  in  fact  the  habitus  of  the  two  species  is  very 
different.  From  a  personal  study  of  the  type  in  the  LeConte 
collection,  the  form  described  as  monachus  by  LeConte,  proves  to 
be  exactly  the  same  as  leucoscelis  and  does  not  approach  gilensis  in 
the  characters  described  above. 

Chlaenius  sanantonialis  n.  sp. — Somewhat  similar  to  cordicollis  but 
smaller  and  more  abbreviated,  dark  steel-blue  in  color  throughout  above, 
the  under  surface  black;  legs  and  antennae  testaceous;  head  and  antennae 
nearly  as  in  cordicollis,  the  prothorax  also  similar  but  much  shorter, 
distinctly  wider  than  long;  elytra  shorter  and  rather  broader,  with  simil- 
arly rounded  humeral  edge  and  widest  slightly  behind  the  middle,  the 
striae  coarser,  more  impressed  and  with  coarser  and  more  conspicuous 
punctures;  intervals  not  so  broad,  feebly  convex  and  with  the  fine 
punctures  less  close-set;  under  surface  and  sexual  characters  nearly 
similar.  Length  (cf)  13.5-14.0  mm.;  width  5.2-5.7  mm.  Texas.  Two 
male  examples,  without  more  accurate  indication  of  locality. 

Distinguishable  from  cordicollis  by  its  more  abbreviated  form, 
shorter  and  relatively  broader  elytra,  with  much  coarser,  more 
impressed  and  more  coarsely  punctate  striae  and  convex,  less  punc- 
tate intervals. 

Chlaenius  sierricola  n.  sp. — Moderately  elongate,  rather  depressed 
on  the  upper  surface,  shining  and  dark  blue  above,  the  elytra  rather 
more  obscure  and  opaculate;  under  surface  black  and  shining,  the  legs 
and  antennae  pale  testaceous;  head  not  longer  than  wide,  smooth  cen- 
trally, rugulose  and  punctate  toward  the  eyes  and  basally;  antenna?  and 
palpi  rather  long  and  slender;  prothorax  two-fifths  wider  than  the  head 
and  a  third  wider  than  long,  the  sides  broadly  rounded,  slightly  converg- 
ing and  distinctly  sinuate  basally,  the  base  slightly  wider  than  the  apex; 
surface  strongly,  rather  closely  punctate,  less  closely  and  rather  more 
irregularly  so  before  about  the  middle;  elytra  three-fourths  wider  than 
the  prothorax,  rather  more  than  one-half  longer  than  wide,  parallel  and 
broadly  arcuate  at  the  sides,  the  basal  and  lateral  beading  forming  a 
sharp  angle;  striae  very  fine,  feebly  impressed,  minutely  punctulate,  the 
intervals  nearly  flat,  rather  closely  punctate,  the  punctures  much  larger

than  those  of  the  striae  though  fine;  pubescence  fulvous;  under  surface 
punctured  throughout,  strongly  and  rather  closely  on  the  sterna;  anterior 
tarsi  (cf)  with  three  dilated  joints.  Length  (c?)  13.5  mm.;  width  5.7 
mm.  California  (Mokelumne  Hill,  Cala'veras  Co.), — Blaisdell. 

There  is  no  species  very  closely  allied  to  the  above,  but  it  may 
be  placed  near  cestivus  for  the  present;  the  strial  punctures  are  very 
minute  and  become  apparent  only  under  careful  observation. 

Chlaenius  cumatilis  ssp.  sparsellus  nov. — Similar  to  cumatilis  in 
general  habitus  but  stouter  and  with  larger  prothorax,  deep  indigo-blue 
and  opaculate  throughout  above;  head  as  in  cumatilis  but  with  the  an- 
tennae slightly  more  elongate;  prothorax  much  larger,  a  fourth  wider 
than  long,  the  sides  more  broadly  and  feebly  rounded,  similar  basally 
and  on  the  disk,  except  that  the  sparse  punctures  are  much  less  coarse; 
elytra  similar  but  broader,  with  the  fine  striae  less  impressed  and  the  fine 
punctures  scattered  over  the  intervals  about  twice  as  numerous;  tarsi 
more  elongate;  under  surface  nearly  similar,  except  that  the  punctures 
are  more  numerous,  especially  on  the  prothorax  throughout.  Length 
(9  )  15.0-16.0  mm.;  width  6.2-6.7  mm.  Arizona. 

Distinguishable  from  cumatilis,  from  the  coast  regions  near  San 
Diego,  by  its  rather  larger  size,  stouter  form,  larger  prothorax, 
which  is  less  rounded  at  the  sides  and  by  the  more  numerous 
punctures. 

Chlaenius  texanellus  n.  sp. — Body  rather  small  in  size  and  moderately 
convex,  rather  shining  and  pure  indigo-blue  anteriorly,  the  elytra  more 
obscure,  blackish-blue  and  opaque;  pubescence  very  short,  fine,  obscure 
fulvous;  head  moderate,  smooth  and  with  rather  large  and  very  convex 
eyes;  antennae  moderate,  fusculate,  the  three  basal  joints  paler;  prothorax 
in  outline  and  sculpture  nearly  as  in  brevilabris,  the  punctures  rather  less 
close-set;  elytra  oblong,  barely  one-half  longer  than  wide,  nearly  one-half 
wider  than  the  prothorax,  the  striae  fine,  rather  strongly  punctate,  the 
punctures  perforate  and  much  wider  than  the  striae;  intervals  flat,  very 
finely,  rather  closely  punctate,  the  punctures  feeble  and  shining  in  the 
opaque  ground;  basal  and  marginal  beads  joining  in  a  broadly  rounded 
angle;  under  surface  black,  shining,  distinctly  and  rather  closely  punc- 
tured throughout,  the  legs  testaceous.  Length  (cf  9  )  9.8-11.0  mm.; 
width  4.3-4.9  mm.  Texas  (Galveston). 

This  species  is  allied  to  brevilabris  but  is  shorter  and  is  always 
of  a  pure  deep  blue  color;  the  elytral  striae  are  finer  and  the  fine 
punctures  of  the  intervals  are  much  less  asperulate.  In  a  series  of 
eleven  specimens  of  brevilabris  at  hand,  the  pronotum  is  always 
bright  green  to  coppery,  while  in  a  series  of  nineteen  examples  of 
texanellus,  the  pronotum  is  deep  bright  violet-blue,  except  in  one 
where  the  blue  is  mixed  with  blue-green.  The  general  outline  is

shorter  and  relatively  broader  than  in  brevilabris  and  the  head  is 
smaller,  with  more  conspicuous  eyes. 

Chlaenius  zunianus  n.  sp. — General  habitus  and  structure  as  in 
tomentosus  Say,  but  more  elongate  and  parallel,  deep  black  above,  beneath 
and  throughout  the  legs  and  palpi,  the  antennae  black,  with  the  basal 
joint  partially  pale;  pubescence  short,  much  less  close  than  in  tomentosus 
and  rather  darker  fulvous  in  color;  head  smoother,  with  only  a  few  very 
minute  punctures  laterally  and  no  rugae;  there  is  an  isolated  cluster  of 
three  or  four  coarser  punctures  about  the  setigerous  fovea  near  each 
eye;  prothorax  in  form  and  sculpture  throughout  almost  as  in  tomentosus, 
except  that  the  punctures  are  everywhere  coarser  in  corresponding  posi- 
tions; elytra  differing  decidedly,  oblong,  parallel,  more  elongate,  more 
rapidly  obtuse  at  apex,  a  fifth  wider  than  the  prothorax,  the  striae, 
strial  punctures  and  humeral  angle  of  the  beading  similar,  the  intervals 
about  one-half  as  densely  and  less  asperately  punctate;  under  surface 
as  in  tomentosus  throughout;  prosternum  margined.  Length  (9)  14.0 
mm.;  width  5.9  mm.  New  Mexico  (Fort  Wingate), — -John  Woodgate. 

Differs  from  tomentosus  in  its  deep  black  color,  more  elongate  and 
abruptly  obtuse,  much  less  densely  punctate  elytra,  rather  more 
transverse  and  somewhat  less  anteriorly  narrowed  and  more 
coarsely  sculptured  pronotum  and  smoother  head.  From  insperatus 
Horn,  it  differs  in  having  the  lateral  and  basal  beads  form  a  sharp 
angle  at  the  humeri  and  in  its  dark  fulvous  and  not  black  vestiture. 

Chlaenius  pimalicus  n.  sp. — Body  somewhat  as  in  chrysopleurns  Chd., 
but  narrower  and  with  uniform  elytral  coloration  and  flatter  intervals, 
shining  and  vivid  metallic  green  throughout  the  head  and  pronotum, 
except  the  convex  lateral  part  of  the  latter  basally,  which  is  cupreous; 
elytra  opaculate,  bright  green  throughout,  the  smoother  marginal  interval 
rather  brighter  green;  under  surface,  legs  and  tarsi  black;  vestiture  short 
but  stiff,  fulvous;  head  smooth,  with  the  frontal  foveae  prolonged  to  a 
point  opposite  the  middle  of  the  eyes,  where  there  is  an  additional  short 
groove  more  inwardly;  antennae  short,  stout,  piceous;  prothorax  in  form 
and  sculpture  almost  exactly  as  in  chrysopleurus  throughout;  elytra 
differing  greatly,  being  narrower,  with  much  less  convex,  more  opaque, 
more  closely  and  much  less  strongly  punctate  intervals,  the  punctures 
of  the  much  shallower  striae  similarly  very  small;  under  surface  nearly 
smooth  but  with  more  coarse  sternal  punctures  than  in  chrysopleurus. 
Length  (9)  13.5-14.0  mm.;  width  5.6-5.8  mm.  Southern  Arizona. 
Three  examples  from  the  Levette  collection. 

The  differences  as  shown  between  this  species  and  three  examples 
of  chrysopleurus  from  Guatemala  and  Honduras,  which  I  have 
before  me,  are  expressed  above,  but  pimalicus  is  very  much  closer 
to  forreri  Bates,  from  Ventanas,  Mexico,  and  may  prove  to  be 
merely  a  subspecies  of  the  latter.  In  forreri  the  elytra  are  described

and  figured  as  virtually  black,  with  the  marginal  interval  bright 
green  and  not  of  a  uniform  vivid  green  throughout  as  in  pimalicus; 
the  tarsi,  also,  are  said  to  be  piceo-rufous. 

Anomoglossus  Chd. 

This  genus  is  well  defined  and  differs  from  Chlcenius  in  the  absence 
of  a  tooth  in  the  emargination  of  the  mentum,  more  uniformly 
punctate  abdomen  and  generally  much  more  deeply  emarginate 
labrum.  The  species  are  more  numerous  than  hitherto  supposed 
and  six  are  now  known;  they  seem  to  be  confined  to  the  nearctic 
faunal  regions  and  are  as  follows: 

Last  joint  of  the  maxillary  palpi  glabrous;  body  larger  in  size;  labrum 
deeply  emarginate 2 

Last  joint  with  sparse  stiff  hairs;  body  of  small  size 4 

2 — Punctures  of  the  elytral  striae  extremely  minute,  confined  to  the  fine 
striae.  Body  narrower  and  less  ventricose,  shining,  metallic  green,

angles,  which  are  slightly  obtuse  and  blunt  but  distinct;  apex  almost 
truncate  and  but  very  little  narrower  than  the  base,  which  is  broadly 
sinuate  medially  as  usual;  surface  strongly  and  somewhat  loosely 
punctate,  gradually  densely  toward  base  and  near  the  median  line, 
which  is  strongly  impressed;  fovese  elongate  and  very  deep,  slightly 
oblique;  elytra  nearly  three-fourths  longer  than  wide,  about  a 
fourth  wider  than  the  prothorax,  parallel  and  broadly  arcuate  at 
the  sides,  obtusely  rounded  at  tip;  striae  very  fine;  interspaces  flat, 
finely,  closely  punctate,  the  punctures  evidently  stronger  than  those 
of  the  striae;  sterna  throughout  with  very  coarse  and  more  or  less 
close-set  punctures,  the  abdomen  finely,  sparsely  punctate.  Length 
(  9  )  11.5  mm. ;  width  4.35  mm.  New  York  (central),  delectans  n.  sp. 

Punctures  of  the  elytral  striae  strong  and  coarser,  rather  wider  than  the 
striae  basally 3

ately shining  anteriorly,  the  elytra  very  dull  and  blackish-blue,  with 
moderately  long  and  rather  fine,  dull  fulvous  vestiture;  under 
surface  and  legs  throughout  as  in  the  preceding;  head  three-fifths 
as  wide  as  the  prothorax,  rather  rugulose,  the  occiput  transversely 
and  strongly  punctate;  mandibles  rather  elongate;  frontal  foveae 
very  small;  antennae  long  and  very  slender,  testaceous;  prothorax 
very  nearly  as  long  as  wide,  the  sides  broadly  rounded,  gradually 
converging  anteriorly  from  the  point  of  greatest  width,  which  is  well

base,  which  is  transverse,  becoming  anteriorly  oblique  laterally,  the 
angles  distinctly  rounded;  side  margins  more  reflexed  basally;  surface 
nearly  as  in  the  preceding,  except  that  the  strong  median  stria  is

arcuate  sides,  three-fifths  longer  than  wide,  nearly  one-half  wider  than 
the  prothorax;  striae  deep;  intervals  not  quite  flat,  finely  and  very 
closely  punctate,  the  punctures  very  much  smaller  than  those  of 
the  striae;  first  three  joints  of  the  anterior  tarsi  (cf)  dilated  and  very 
gradually  diminishing  in  width.  Length  (cf)  15.0  mm.;  width  6.25 
mm.  Mississippi  (Vicksburg) gravis  n.  sp. 

Body  somewhat  as  in  the  preceding  in  general  habitus  but  smaller  and 
much  narrower  in  build,  the  anterior  parts  more  brilliantly  cupreous, 
generally  greenish  toward  the  sides,  the  elytra  less  opaque  and  of  a 
clearer  indigo-blue;  head  smaller  but  otherwise  nearly  similar, 
smoother,  the  rugae  of  the  preceding  not  visible;  prothorax  nearly 
similar,  except  that  the  sides  are  more  evenly,  feebly  arcuate  from 
near  the  base  to  the  apex  and  the  side  margins  are  not  or  only  very 
slightly  more  reflexed  basally;  surface  otherwise  similar;  elytra 
nearly  similar  but  much  narrower,  with  finer  and  more  deeply 
impressed,  still  more  strongly  and  closely  punctate  striae  and  more

rounded;  reflexed  margin  feebly  elevated  basally,  the  surface  as 
long  as  wide,  nearly  flat,  densely  punctate,  with  well  marked  median 
line  and  deep  elongate  foveae;  elytra  oval,  wider  than  the  prothorax, 
with  strongly  marked  and  distinctly  punctate  striae  and  flat,  finely 
and  closely  punctured  intervals.  Length  8-9.5  mm.;  width  3.3- 
4.0  mm. — Description  quoted  from  Dejean.  Georgia,  .amcenus  Dej. 

Labrum  deeply  emarginate;  prothorax  generally  more  narrowed  basally.  .5 

5 — Form  moderately  slender,  not  very  convex,  shining,  metallic  bluish- 
green  anteriorly,  the  elytra  feebly  shining  and  obscure  deep  blue; 
under  surface  black,  closely  punctate  throughout  as  in  all  the 
preceding  species,  the  legs  testaceous;  head  more  than  two-thirds 
as  wide  as  the  prothorax,  smooth  centrally,  punctured  sparsely 
toward  the  eyes  and  across  the  occiput,  the  eyes  only  moderately

Form  more  abbreviated,  the  size  much  smaller;  coloration,  lustre  and 
general  habitus  nearly  similar;  head  relatively  larger,  nearly  four- 
fifths  as  wide  as  the  prothorax,  similarly  punctured;  antennae  slender, 
not  much  over  half  as  long  as  the  body,  testaceous,  clearer  basally; 
prothorax  nearly  similar  in  form  and  sculpture  but  more  nearly  as 
long  as  wide,  the  sides  at  base  becoming  straight  only  at,  and  not 
for  some  distance  before,  the  basal  angles,  which  are  distinctly 
obtuse  though  sharply  marked  and  not  blunt;  base  becoming  ar-

These  species  seem  to  be  amply  distinct  among  themselves  and 
doubtless  a  number  of  others  are  already  included  in  collections. 
The  subacute  lobes  of  the  labrum,  in  all  the  species,  have  a  loose 
tuft  of  stiff  yellow  bristles,  which  are  different  from  the  ordinary 
setae  of  the  labral  apex. 

Brachylobus  Chd. 

The  mentum  in  this  genus  is  so  radically  different  from  the  usual 
type  in  this  subfamily,  that  a  separate  tribe  might  be  organized 
to  include  it  alone,  so  far  as  now  known.  The  surface  of  the 
mentum  is  smooth  and  has  two  very  deep  impressed  perforations; 
the  apex  has  an  extremely  shallow  sinus,  with  very  short  angulate 
lateral  lobes  and  is  completely  edentate.  The  following  is  a  sub- 
species of  the  well  known  lithophilus: 

Brachylobus    lithophilus   ssp.   indigaceus   nov. — Body   nearly   as   in

head  rather  smaller  and  with  somewhat  less  prominent  eyes;  prothorax 
similar  throughout  but  not  quite  so  short  or  transverse;  elytra  similar  but 
slightly  less  obtusely  rounded  at  tip  and  with  the  striae  sensibly  finer  and 
much  less  strongly  punctate,  the  intervals  flat,  not  quite  so  densely 
punctate;  punctures  of  the  under  surface  scarcely  so  large  but  similarly 
disposed.  Length  (cf  9  )  8.5-9.0  mm.;  width  3.7-4.0  mm.  Texas. 
Two  examples. 

My  series  of  lithophilus  is  from  New  Jersey,  Pennsylvania  and 
Indiana;  indigaceus  is  a  more  southern  development  of  the  stem 
form.  Caurinus  Horn,  differs  in  the  form  of  the  prothorax. 

Subfamily  MICRATOPINI  nov. 

Middle  coxal  cavities  entirely  inclosed  by  the  sterna,  the  suture 
very  fine  and  close.  Head  with  a  single  supra-orbital  seta.  Meso- 
sternal  epimera  very  narrow,  indistinct;  elytra  covering  the  ab- 
domen. Mandibles  without  an  external  seta.  Posterior  coxae  con- 
tiguous. Elytral  margin  continuous,  without  an  internal  plica. 
Last  joint  of  the  palpi  minute,  slender,  oblique  and  inserted  within 
a  cavity  at  the  tip  of  the  penultimate.  Body  minute;  integuments 
thin;  facies  nearly  as  in  the  Lebiinae. 

Following  the  order  of  characters  now  usually  admitted  in  the 
classification  of  the  Carabidae,  the  very  small  species  serving  as  the 
type  of  the  new  subfamily  here  proposed,  is,  as  may  be  surmised, 
extremely  isolated,  for,  with  palpi  nearly  as  in  the  Bembidiinae 
and  habitus  of  the  body  nearly  as  in  the  Lebiinae,  we  have  standing 
out  very  clearly  at  the  smooth  sides  of  the  head,  near  the  eye, 
only  a  single  long  seta,  exactly  as  in  all  the  other  CARABID.E  CON- 
JUNCT^ UNISETOS/E.* 

Micratopus  n.  gen. 

Body  very  small  and  feebly  convex,  oblong-elongate,  with  thin 
integuments,  rather  small  short  head  and  large  convex  eyes.  Mouth 
organs  rather  crowded.  Mentum  moderate,  nearly  flat,  oval, 
slightly  transverse,  with  a  moderate  and  rather  deep  edentate 
sinus,  the  lobes  sharply  acuminate.  Ligula  very  small,  slender,  the 
paraglossae  small,  externally  pointed  at  apex.  Basal  joint  of  the 
outer  maxillary  lobe  stout,  oval,  the  last  joint  short,  narrower,

Labial  palpi  with  the  first  joint  minute,  the  second  large,  inflated, 
pubescent,  the  third  joint  minute,  slender,  projecting  obliquely 
from  the  apex  of  the  second.  Maxillary  palpi  moderately  long, 
coarsely  pubescent  throughout,  the  second  joint  moderately  slender, 
the  third  of  equal  length,  moderately  stout,  gradually  narrowed 
basally,  the  fourth  minute,  aciculate,  oblique,  extending  from  a 
cavity  in  the  tip  of  the  third.  Mandibles  small,  strongly  arcuate, 
almost  entirely  hidden  under  the  labrum  in  repose,  bifid  at  tip. 
Labrum  transverse,  strongly  convex,  smooth,  deeply  sinuate 
medially.  Epistoma  flat,  slightly  wider  than  long,  arcuate  at  tip, 
the  suture  fine,  the  frontal  foveae  obsolete,  represented  by  large  and 
feeble  impressions.  Eyes  notably  large  though  only  moderately 
prominent,  the  facets  very  distinct  and  convex.  Antennae  long, 
very  slender,  filiform,  pubescent  throughout,  the  first  joint  subequal 
to  the  fourth  and  longer  than  either  the  second  or  third,  which  are 
nearly  equal.  Prothorax  transversely  and  feebly  obtrapezoidal, 
with  a  marginal  seta  before  the  middle  and  another  at  the  hind 
angles.  Scutellum  ogival,  entering  well  between  the  elytra,  which 
are  feebly  striate,  with  obtuse  apex,  rounded  sutural  angles  and  a 
small  subapical  discal  puncture  at  the  third  stria,  the  scutellar  stria 
completely  wanting  but  with  the  fovea  very  exceptional,  being  in 
the  form  of  a  small  setigerous  tubercle  arising  from  the  bottom 
of  a  rounded  depression;  sides  with  about  four  granuliferous  seti- 
gerous foveae  basally  and  two  or  three  apically,  the  latter  bearing 
very  long  setae.  Prosternum  unusually  long  before  the  coxae,  the 
process  unmargined.  Abdomen  uniformly  punctulate  and  minutely 
setigerous  throughout,  with  a  close-set  pair  of  apical  setae  at  each 
side,  apparently  in  both  sexes.  Sexual  characters  not  apparent. 
Legs  moderate,  the  femora  strongly  compressed,  the  tibiae  simple, 
with  small  slender  spurs,  the  tarsi  rather  long,  very  slender  through- 
out, the  first  joint  of  the  posterior  subequal  in  length  to  the  entire 
remainder,  the  fifth  a  little  longer  than  the  two  preceding  combined  ; 
claws  very  small  and  slender.

alutaceous  and  micro-reticulate;  antennae  very  slender  and  filiform,  nearly 
three-fifths  as  long  as  the  body;  prothorax  one-half  wider  than  long, 
widest  near  apical  third,  where  the  sides  are  rather  strongly  rounded, 
thence  moderately  converging  and  more  feebly  arcuate  to  the  basal 
angles,  which  are  obtuse  but  distinct  and  subprominent;  apex  broadly 
sinuate,  barely  as  wide  as  the  base;  surface  smooth  and  polished,  with 
strong  abbreviated  median  stria  and,  at  the  basal  margin  near  each  side, 
a  small  feeble  fovea;  elytra  nearly  one-half  longer  than  wide,  parallel, 
with  nearly  straight  sides  and  abruptly  very  obtuse  apex,  a  third  to 
nearly  half  wider  than  the  prothorax,  the  strise  rather  broadly  impressed 
and  not  at  all  sharply  defined;  humeri  right  and  narrowly  rounded.

of  fallen  leaves  in  one  of  the  narrow  ravines  south  of  the  town. 


Ill— A   REVISION   OF  THE   NEARCTIC   HARPALIN^E. 

It  is  hoped  that  in  judging  the  following  work,  some  allowance 
will  be  made  for  inherent  difficulties,  which  are  sufficiently  well 
known  to  all  those  who  have  given  the  subfamily  serious  considera- 
tion. The  apparent  monotony  and  indefiniteness  of  the  species, 
has  served  to  deprive  this  section  of  the  Carabidse  of  much  con- 
sideration, for  there  is  not  even  the  compensation,  offered  by  the 
equally  indefinite  Chlaeniid  species,  of  having  an  attractive  colora- 
tion. I  have  found  the  study  of  the  Harpalids  very  interesting; 
they  are  by  no  means  devoid  of  very  marked  structural  diversity. 

Subfamily  HARPALIN^:. 

It  seems  preferable  to  regard  the  major  groups  of  Carabidse,  which 
were  termed  tribes  by  LeConte  and  Horn,  as  subfamilies,  after  the 
general  European  custom.  The  subfamilies  can  then  be  sub- 
divided into  tribes  and  these  into  groups.  At  any  rate,  I  find  this 
to  be  a  more  convenient  system  in  the  case  of  such  an  unwieldy 
complex  as  the  Harpalinae  and  the  suggested  method  of  subdivision 
seems  also  to  express  relative  weights  more  consistently. 

The  classification  of  the  Carabidse  now  in  vogue  has  been  of 
very  gradual  evolution.  The  arbitrary  arrangement  of  the  earlier 
authors  was  measurably  improved  by  the  work  of  LeConte  (Trans. 
Am.  Phil.  Soc.,  1853),  to  such  a  degree  in  fact  that  Lacordaire  in- 
serted the  arrangement  of  our  able  and  honored  predecessor  in  its 
entirety,  as  an  appendix  to  the  first  volume  of  his  still  invaluable 
work  on  the  genera  of  the  Coleoptera.  It  is  easy  to  trace  some  sub- 
sequent generalizations  from  this  early  work  of  LeConte.  For 
example,  further  examination  of  the  character  relating  to  the 
mesosternal  parapleura  led  to  the  detection  of  the  fundamental 
structure  now  utilized  for  the  division  of  our  Carabidse  into  two 
sections,  as  stated  in  the  classification  of  LeConte  and  Horn, 
based  upon  the  extension  of  the  mesosternal  epimera  in  the  direction 
of  the  coxse.  The  other  two  discoveries  of  the  systematists  just 
mentioned,  that  have  given  us  our  present  arrangement — probably 

45 


46  MEMOIRS  ON  THE  COLEOPTERA 

the  most  natural  that  can  be  devised,  relate  to  the  existence  of 
one  or  two  supra-orbital  setse — extremely  significant  in  the  second 
subdivision  of  the  family  but  of  no  value  in  the  first — and  the 
presence  or  absence  of  a  postero-external  elytral  plica.  These 
very  important  discoveries  give  us  the  means  of  resolving  the 
family  into  several  very  clearly  demarcated  sections.  I  would 
suggest  in  this  connection  that  the  genus  Pseudomorpha  be  separated 
from  the  Carabidae  to  form  a  distinct  family.  It  does  not  fall  in 
line  with  the  true  Carabids  very  well  either  in  structure  or  facies. 

The  Harpalinse,  as  here  considered,  embrace  all  Carabids  in 
which  the  mes-epimera  fail  to  attain  the  coxae  and  are  narrow  and 
parallel  in  form  and  also  in  which  the  head  has  but  a  single  supra- 
orbital  seta,  the  mandibles  devoid  of  an  external  setigerous  punc- 
ture, the  posterior  coxas  contiguous  and  the  elytra  without  a  postero- 
external  plica.  I  have  no  means  of  verifying  the  opinion  of  Dr. 
Horn  (Tr.  Am.  Ent.  Soc.,  1881,  p.  175)  that  the  singular  African 
genus  Glyptus,  having  no  seta  on  the  second  labio-palpal  joint, 
is  a  component  of  the  subfamily,  but  am  inclined  to  believe  that  the 
rernarkable  group  of  genera  clustering  about  the  European  Ditomus 
should  be  excluded  and  form  a  subfamily  by  themselves,  because 
of  the  strongly  pedunculated  body,  long  antennas,  occasional  very 
striking  modifications  of  the  epistoma  and  mandibles,  the  peculiar 
coarse  sculpture  of  the  body  and  the  marked  departure  in  general 
habitus.  Although  most  of  the  Ditomid  genera  are  represented  in 
the  material  at  hand,  I  have  therefore  thought  best  not  to  include 
them  within  the  scope  of  the  subfamily  as  here  considered.  All 
of  the  European  tribes  of  the  subfamily,  as  thus  restricted,  occur 
in  North  America,  but  there  are  a  few  American  tribes  such  as 
Cratocarini  which  do  not  occur  in  the  old  world. 

In  the  table  of  tribes  given  below,  it  will  be  noted  that  the 
division  heretofore  proposed  into  three  groups  of  genera,  depending 
upon  the  structure  of  the  male  tarsi,  has  been  abandoned  and  a 
succession  of  tribes  defined  upon  more  restricted  sexual  characters 
of  the  same  kind,  the  two  principal  divisions,  however,  being  based 
upon  the  setee  of  the  second  labio-palpal  joint,  first  suggested  by 
Bates.  The  full  importance  of  this  character,  which  widely  shifts 
the  positions  of  several  important  genera  such  as  Polpochila  and 
Agonoderus  into  more  congenial  surroundings,  escaped  the  attention 


HARPALIN^E  47 

of  Dr.  Horn,  by  whom  it  appears  to  have  been  first  brought  to 
notice  and  was  employed  by  that  author  merely  in  the  separation 
of  genera  which  seemed  to  be  otherwise  closely  allied. 

In  the  Harpalinse  there  are  numerous  confusing  parallelisms  of 
structure,  appearing  in  genera  evidently  widely  separated  in  the 
present  stage  of  evolution  and  probably  reversional  in  nature,  or 
indicative  of  like  conditions  of  environment  during  the  progress 
of  evolutionary  changes,  such  for  instance  as  the  occurrence  of 
series  of  setigerous  substrial  punctures  in  such  widely  separated 
types  as  Stenomorphus,  Selenophorus  and  Philodes,  or  the  occurrence 
of  the  trifid  anterior  tibial  spur  in  various  not  closely  related  genera 
within  the  tribe  Anisodactylini,  also  occurring  in  the  Amarid  genus 
TricEna  and  so  of  no  special  significance  in  the  estimation  of  generic 
relationship.  Again,  the  presence  of  the  enlarged  basal  joint  of 
the  anterior  tarsi,  especially  of  the  female,  characterizing  the  highly 
specialized  genera  Stenomorphus  and  Gynandropus,  as  well  as 
Gynandrotarsus  harpaloides  of  the  Anisodactylini,  and,  finally,  the 
occurrence  of  the  rare  seta  at  the  hind  angles  of  the  prothorax  in 
the  indubitable  Anisodactylid  Diachromus  and  in  Trichocellus  of 
the  Acupalpini.  Dicheirotrichus  is  somewhat  intermediate  between 
these  two  genera,  tending  to  unite  the  two  divisions  based  upon  the 
labial  palpi  and,  as  significant  in  this  respect,  there  seem  to  be  only 
three  long  anterior  setae  on  the  second  labio-palpal  joint;  the  male 
tarsi,  also,  are  not  so  purely  Anisodactylid  as  in  Diachromus, 
although  the  rather  even  distribution  of  the  long  hairs  of  the  soles 
would  seem  to  betoken  somewhat  more  of  an  Anisodactylid  than 
Acupalpid  affinity,  the  general  habitus  of  the  body,  however,  being 
evidently  more  nearly  that  of  the  Acupalpini,  to  which  tribe  it  is 
here  attached. 

The  various  tribes  of  the  Harpalinse,  so  far  as  represented  by 
material  accessible  to  me,  may  be  defined  as  follows.  The  exotic 
groups,  whether  tribes  or  genera,  in  this  and  all  subsequent  tabular 
statements,  are  indicated  by  a  prefixed  asterisk  as  usual :

Second  joint  bisetose  in  front 6 

2 — Middle  tarsi  (cf )  not  modified  in  vestiture  beneath  and  undilated, 
the  anterior  sometimes  so  modified,  however,  as  in  Geopinus;  ab- 
domen generally  with  accessory  setae  as  in  a  large  division  of  Har- 
palus;  basal  angles  of  the  prothorax  generally  acutely  rectangular 
or  acutely  subeverted,  the  prosternum  short DAPTINI

Middle  tarsi  (cf)  biseriately  squamulose  beneath 3 

Middle  tarsi  (cf )  with  dense  uniform  pads  of  squamiform  pubescence

3 — Elytra  without  series  of  substrial  setigerous  punctures,  generally  with 

•a  single  puncture  at  or  near  the  second  stria  on  the  third  interval; 

prosternum  normally  short  before  the  coxae HARPALINI 

Elytra  with  series  of  substrial  punctures 4 

4 — Prosternum  normally  short  before  the  coxae;  elytral  series  always 
three  in  number  on  each SELENOPHORINI 

Prosternum  greatly  elongated  before  the  coxae;  basal  joint  of  the  anterior 
tarsi  unusually  developed,  especially  in  the  female  as  in  Gynandropus 
of  the  Selenophorini  and  as  reappearing  in  some  of  the  Anisodactylini, 
such  as  Triplectrus  (Gynandrotarsus};  series  of  elytral  punctures 
usually  two  in  number STENOMORPHINI 

5 — Anterior  and  middle  tarsi  (cf)  always  dilated;  body  more  Harpalus- 
like  in  facies  than  in  either  of  the  two  preceding  tribes. 

ANISODACTYLINI 

6 — Frontal  impressions  isolated  or  continued  obliquely  backward  in  a 
more  or  less  fine  canaliculation  to  the  middle  of  the  eyes;  tarsi 
variously  modified  sexually;  body  always  small  to  very  small  in  size. 

ACUPALPINI 

Frontal  impressions  continued  obliquely  backward  to  the  occiput  or 
posterior  limit  of  the  eyes;  tarsi  not  or  but  very  slightly  modified 
sexually;  body  rather  large  in  size  to  moderately  small. .  CRATOCARINI 

It  seems  necessary  to  use  the  name  Cratocara  of  LeConte,  for 
what  is  now  known  in  the  lists  as  Polpochila  Sol.,  for,  on  reading  the 
diagnosis  of  the  latter  genus,  which  is  probably  confined  to  the  west 
coast  of  South  America,  I  fail  to  perceive  any  close  relationship 
with  the  so-called  Polpochila  capitata  Chd.  The  description  of 
Polpochila,  as  given  by  Lacordaire,  is  as  follows: 

Mentum  transverse,  narrowly  and  deeply  emarginate  and  with  a 
median  tooth  which  is  triangular  and  simple,  its  lateral  lobes  rounded 
externally,  obtuse  at  tip  and  having  a  small  tooth  on  the  inner  side. 
Ligula  free,  very  prominent,  rather  broad,  scarcely  notched  at  tip,  the 
paraglossae  large,  spatuliform  and  internally  recurved.  Last  joint  of 
the  palpi  oblong-oval,  equal  to  the  preceding.  Labrum  transverse, 
angularly  notched.  Head  short.  Antenna?  short,  gradually  increasing 
in  thickness,  the  joints  3-6  conical,  equal,  7-10  larger  and  shorter  than 
the  preceding,  suboval  and  truncate  at  base  and  apex.  Prothorax 
transverse,  scarcely  narrowed  behind,  almost  straight  at  the  sides,  trans- 
versely truncate  at  base  and  separated  from  the  elytra  by  a  distinct 
interval.  Elytra  parallel,  rounded  at  apex.  Legs  short,  the  anterior 
stouter,  with  the  tibiae  sensibly  triangular,  the  four  posterior  tibiae 
spinose.  Tarsi  filiform,  the  four  basal  joints  of  the  anterior  short, 
strongly  triangular,  with  the  first  two  a  little  longer  than  the  others. 

Solier  assigns  to  this  genus  only  a  very  small  insect  (P.  parallela), 


HARPALIN^E  49 

3  mm.  in  length,  of  a  rather  brilliant  black  color,  native  to  the 
southern  provinces  of  Chile  and  of  which  he  had  only  seen  a  single 
example  of  undetermined  sex.  It  was  placed  among  the  Feroniids 
by  Lacordaire.  In  view  of  the  size  of  the  body,  the  singular 
structure  of  the  antennae  and  the  extreme  southern  and  isolated 
habitat,  I  think  there  can  be  but  little  doubt  that  we  have  been  in 
error  in  assigning  to  Polpochila  our  large  Melanotus  erro  Lee.  (capi- 
tata  Chd.),  subsequently  given  the  generic  name  Cratocara  by 
LeConte  (Sm.  Misc.  Coll.  140,  p.  n,  1866)  because  of  the  previous 
use  of  Melanotus.  There  can  be  no  question  concerning  the  close 
relationship  of  Pogonodaptus  Horn,  with  Cratocara,  as  stated  by 
Bates.  It  has  no  affinity  whatever  with  Daptus. 

Tribe  DAPTINI. 

The  genera  of  this  tribe,  which  abound  and  are  greatly  diversified 
in  America,  but  represented  in  the  palaearctic  fauna  by  the  single 
genus  Daptus,  may  be  distinguished  among  themselves  as  follows: 

Tarsi  thick,  the  posterior  rapidly  tapering  from  base  to  apex,  the  anterior 
clothed  beneath  in  the  male  with  confused  erect  squamiform  hairs; 
anterior  tibiae  with  a  ciliate  terminal  plate  in  both  sexes,  the  tibial 
surfaces  not  peculiarly  modified Geopinus 

Tarsi  slender,  the  posterior  filiform,  the  anterior  apparently  never  hairy 
beneath,  the  anterior  tibiae  without  lamelliform  extension,  though 
peculiarly  modified  apically  in  Nothopus 2 

2 — Anterior  and  middle  tibiae  thickened,  densely,  coarsely  punctured  and 
spinulo-setulose  over  their  posterior  and  anterior  surfaces  respec- 
tively; body  subpedunculate *Daptus 

Anterior  and  middle  tibiae  not  specially  modified  on  their  lateral  surfaces; 
body  not  pedunculated 3 

3 — Hind  angles  of  the  prothorax  right  or  acute,  frequently  everted; 
elytra  oblong,  the  humeri  distinct,  the  hind  wings  always  well 
developed 4 

Hind  angles  very  obtuse  but  never  at  all  broadly  rounded;  elytra  oval, 
with  rounding  humeri,  the  hind  wings  apparently  vestigial;  mentum 
edentate 8 

4 — Mentum  edentate;  ligula  small  and  slender,  much  shorter  than  the 
large  and  usually  thickened  ciliate  paraglossae 5 

Mentum  with  a  long  and  very  acute  tooth;  ligula  rather  broader,  not 
evidently  expanded  at  tip,  exactly  equal  in  length  to  the  paraglossae.  7 

5 — Body  somewhat  as  in  Daptus,  narrower  than  in  any  of  the  following 
genera,  the  head  large,  the  prothorax  cordate,  the  sides  sinuate 
before  the  right  and  very  sharp  basal  angles;  head  without  projec- 
tions above  the  antennae,  which  are  slender  and  filiform;  elytra 
rather  short,  wider  than  the  prothorax,  the  base  much  wider  than 

T.  L.  Casey,  Mem.  Col.  V,  Oct.  1914. 


5O  MEMOIRS  ON  THE  COLEOPTERA 

the  thoracic  base,  simply  striate,  the  first  stria  bifurcating  at  base 
because  of  union  with  the  scutellar  stria,  the  second  with  a  single 
setigerous  puncture,  which  is  unusually  posterior  and  near  the 
summit  of  the  declivity,  the  apex  obliquely  ogival,  the  sinus  broad 
and  extremely  feeble;  legs  moderate,  the  tibiae  and  tarsi  slender,  the 
basal  joint  of  the  posterior  tarsi  not  as  long  as  the  next  two. 

*Cratognathus 

Body  stout,  the  elytral  and  thoracic  bases  not  differing  much  in  width; 
elytra  with  numerous  punctures  bearing  long  setae 6 

6 — Anterior  tibiae  rather  slender,  of  the  usual  form,  not  modified  ex- 
ternally or  at  apex;  body  nearly  as  in  Cratacanthus  in  outline. 

Piosoma 

Anterior  tibiae  with  an  obtuse  prominence  on  the  external  edge,  the  outer 
apical  angle  greatly  produced  in  an  obtusely  pointed  and  slightly 
curved  process;  body  larger,  broader  and  still  more  compact. 

Nothopus 

7 — Body  oblong,  stout,  very  convex,  shining,  the  elytra  deeply  striate 
but  without  discal  punctures  of  any  kind,  even  the  single  puncture  of 
Cratognathus  and  many  Harpali  being  absent,  the  foveae  of  the 
marginal  series  irregular,  the  series  uninterrupted  medially;  legs 
moderate,  without  special  modification Cratacanthus 

8 — Body  elongate-suboval,  convex,  the  legs  rather  slender,  the  anterior 
tibiae  unmodified  sexually,  slender,  with  a  small  slender  terminal 
spur;  elytra  with  serial  punctures  on  the  alternate  intervals  toward 
apex  only Glanodes 

The  above  outline  of  Cratognathus  Dej.,  is  drawn  from  a  pair 
that  I  took  at  Wellington,  near  Cape  Town,  South  Africa;  the  species 
is  probably  capensis  Cast.  As  stated  by  Lacordaire,  Dejean  was 
mistaken  in  assuming  that  his  type  species  was  from  South  America. 

Geopinus  Lee. 

The  body  is  large  in  size,  very  stout  and  convex  and  of  a  peculiar 
pale  tawny  yellow  color  throughout,  with  the  exception  of  some 
indefinite  shading  occasionally  on  the  pronotum  and  elytra.  The 
mentum  is  devoid  of  any  trace  of  tooth,  as  in  all  the  genera  of 
the  tribe  excepting  Cratacanthus,  the  head  large,  with  relatively 
rather  small  but  prominent  eyes,  the  palpi  moderately  slender,  the 
second  of  the  labial  with  numerous  bristling  setae,  the  last  joint 
of  both  with  but  few  short  erect  setae,  the  ligula  long,  gradually 
feebly  dilated  apically,  free  and  with  two  very  long  setae  at  the 
truncate  apex,  the  paraglossae  flat,  truncate,  not  very  wide  and 
shorter  than  the  ligula.  The  antennae  are  relatively  very  short  and 
rather  thick,  though  filiform  and  the  labrum  is  shallowly  but  acutely 


HARPALIN/E  51 

emarginate  medially  at  tip,  the  frontal  impressions  rather  large, 
deeply  impressed  and  isolated.  The  prothorax  is  nearly  as  in 
Daptus  and  Cratacanthus  and  the  elytra  are  of  the  usual  Har- 
palid  type;  there  is  a  single  puncture  on  the  second  stria  behind 
the  middle.  The  legs  are  rather  short  and  notably  stout,  the 
femora  all  rather  distinctly  swollen,  the  tibiae  gradually  dilated 
distally,  the  anterior  serrulate  externally,  with  a  small  emargination 
just  before  a  singular  oblique  concave,  lamelliform  apical  extension, 
the  plate  densely  fimbriate  with  short  spinuliform  setae;  the  terminal 
spur  of  the  anterior  is  single  and  feebly  swollen  at  each  side  near 
the  base,  those  of  the  intermediate  and  posterior  two  in  number, 
long  and  very  slender  on  the  former  and  very  stout  on  the  latter. 
The  anterior  tarsi  of  the  male  are  rather  short  and  chick,  with  mod- 
erately dilated  joints,  the  basal  nearly  as  long  as  the  next  two  but 
not  inflated,  spinose  beneath  and  devoid  of  squamae;  joints  2-4 
transverse  and  densely  clothed  with  confused  squamules,  the 
second  in  apical  half  only,  the  intermediate  much  longer  and  more 
filiform  than  the  anterior  or  posterior,  both  the  latter  and  inter- 
mediate completely  devoid  of  squamules.  The  tarsi  of  the  female 
are  nearly  as  in  the  male  but  rather  less  dilated  throughout  and 
especially  the  anterior,  all  devoid  of  squamules.  The  tarsal  claws 
are  long,  divaricate,  extremely  slender  and  evenly  arcuate.  The 
single  species  may  be  known  as  follows: 

Stout,  oblong-oval,  very  convex,  not  very  shining,  pale  tawny-yellow  in 
color,  the  elytra  each  broadly  and  very  indefinitely  clouded  with 
darker  brown  discally,  the  pronotum  clouded  at  apex,  except  at  the 
sides,  and  thence  broadly  posteriorly  to  behind  the  middle;  head 
(c?1)  three-fourths  as  wide  as  the  prothorax  or  four-fifths  (9  ),  the 
prothorax  relatively  smaller  in  the  latter  sex;  antennae  extending

than  long,  the  sides  rounded  anteriorly,  feebly  converging  and 
slightly  sinuate  thence  to  the  hind  angles,  which  are  but  little  more 
than  right  and  slightly  blunt  at  tip,  the  lateral  gutter  rather  broad 
throughout;  base  transverse,  strongly  margined,  the  apex  sinuato- 
truncate;  surface  deplanate  from  the  large  but  vague  foveae  to  the 
hind  angles  and  impunctate;  elytra  much  wider  than  the  prothorax, 
oblong-oval,  with  arcuate  sides  and  obtusely  rounded  apex,  two- 
fifths  longer  than  wide,  the  sides  becoming  straight  and  oblique  near 
the  base;  sinus  narrow  but  rather  deep;  surface  coarsely,  deeply 
striate,  the  scutellar  stria  deep  and  long,  uniting  with  the  first,  which 
becomes  therefore  symmetrically  bifurcate  at  base,  the  two  lateral 
striae  on  the  flanks  abruptly  very  fine  and  feeble,  the  marginal  foveae

This  forms  another  instance  of  anciently  identical  stocks  gradu- 
ally becoming  different  on  opposite  slopes  of  the  Appalachian 
system,  as  shown  by  Tetraopes  tetrophthalmus  and  iowensis  (Mem. 
Col.  IV,  p.  386)  and  also  perhaps  by  Cicindela  levettei,  when  com- 
pared with  sexguttata,  but  in  the  latter  case  the  differences  have 
become  specific,  as  shown  by  the  very  much  longer  tibiae  in  levettei 
as  well  as  the  constantly  different  coloration. 

Daptus  Fisch. 

This  genus  includes  but  few  isolated  species,  only  occurring,  so 
far  as  known,  in  the  palsearctic  fauna,  where  however  they  are 
widely  diffused.  The  type  of  the  genus,  Daptus  vittatus  Fisch., 
with  several  varieties,  and  pictus,  of  the  same  author,  are  the  only 
species  now  known.  The  body  is  rather  small  in  size,  oblong- 
elongate  and  parallel  in  form,  moderately  convex  and  shining,  the 
elytra  pale  in  color  as  in  Geopinus  and  with  nearly  corresponding 
darker  discal  parts.  The  head  is  large,  the  eyes  moderate  and 
prominent,  the  mandibles  well  developed,  arcuate  at  tip,  the 
labrum  feebly  sinuate  and  the  frontal  impressions  very  shallow 
and  diffuse;  there  is  a  pointed  projection  above  the  point  of  antennal 
insertion  and  the  antennae  are  short  and  rather  stout  but  filiform, 
with  the  third  joint  as  long  as  the  next  two  combined.  The  mentum 
is  not  very  large,  unusually  short,  the  sinus  arcuate  at  the  bottom 
but  not  dentate,  the  ligula  rather  widely  expanded  at  tip  and 
longer  than  the  paraglossae,  which  are  small  in  size;  the  palpi  are 
rather  slender;  the  prothorax  is  transverse,  cordate,  about  as  wide 
as  the  elytra,  with  the  converging  sides  sinuate  before  the  basal 
angles,  which  are  right,  not  rounded  and  even  slightly  reflexed; 
the  elytra  are  parallel,  abruptly  very  obtuse  at  apex,  the  sinus 


HARPALIISLE  53 

obsolete,  the  striae  rather  deep,  feeble  laterally,  the  scutellar  strong, 
tending  to  unite  with  the  first,  which  is  deflexed  basally;  the  striae 
are  obsoletely  and  finely  punctulate  and,  in  apical  half  near  the 
second,  there  are  about  four  and  basal  half  of  the  third  two, 
rather  large  impressed  setigerous  punctures;  the  marginal  foveae 
are  very  small  and  are  present  only  near  base  and  apex.  The  legs 
are  thick  and  rather  short,  the  femora  not  notably  stout,  the 
anterior  and  middle  tibiae  somewhat  inflated,  the  former  on  the 
posterior  face  and  the  latter  on  the  anterior  face,  covered  thickly 
with  short  stiff  spinules  arising  from  coarse  deep  punctures;  all 
the  tarsi  are  spinose  beneath  in  both  sexes,  the  anterior  not  dilated 
in  the  male  though  rather  thick  short  and  tapering,  the  others 
slender  and  filiform,  the  basal  joint  of  the  posterior  not  as  long  as 
the  next  two.  The  prosternal  process  is  unusually  narrow  and 
constricted  between  the  coxae. 

Piosoma  Lee. 

The  body  here  is  very  much  as  in  Cratacanthus  in  external  form 
but  somewhat  stouter,  strongly  convex,  shining,  the  head  moder- 
ately large,  with  rather  prominent  eyes  and  slender  filiform  com- 
pressed antennae,  the  third  joint  but  little  longer  than  the  second 
or  fourth,  the  upper  surface  with  fine  punctures  throughout  and  a 
transverse  interrupted  series  of  coarse  punctures  on  a  line  with 
the  posterior  limit  of  the  eyes;  the  frontal  foveae  are  small  and 
punctiform;  the  prothorax  is  transverse,  equal  in  width  to  the  elytra 
or  nearly  so,  the  sides  feebly  converging  and  broadly  sinuate 
posteriorly  to  the  right  and  sharply  marked  angles,  the  surface 
with  numerous  very  coarse  punctures  toward  base  and  sides,  the 
base  transverse  and  margined  throughout,  the  apex  feebly  sinuate 
and  with  broadly  rounded  angles.  The  elytra  are  notably  short, 
parallel,  very  obtusely  rounded  at  apex,  the  sinus  completely 
obsolete.  The  legs  are  moderate  in  length,  not  very  thick,  the 
hind  tarsi  filiform,  with  the  basal  joint  but  little  longer  than  the 
second.  All  the  coarse  punctures  of  the  upper  surface  bear  very 
long  bristling  setae,  those  at  the  sides  of  the  prothorax  forming  a 
conspicuous  loose  fringe.  There  seem  to  be  three  species  as  follows:

converging  and  broadly  sinuate  basally;  surface  steeply  declivous

nearly  a  third  longer  than  wide,  parallel,  very  broadly  rounded  at 
apex  and  with  dentiform  humeral  angles,  the  striae  very  coarse  and 
deep,  the  scutellar  finer,  long,  generally  joining  the  first;  intervals 
feebly  convex,  each  with  a  regular  and  widely  spaced  medial  series  of 
very  coarse  setigerous  punctures;  marginal  interval  with  scattered 
smaller  punctures.  Length  (c?  9  )  7.8-11.7  mm. ;  width  3.4-4.6  mm.

alternata  Lee. 

The  description  of  alternata,  which  I  have  not  seen,  is  taken  from 
the  original;  it  seems  to  be  extremely  rare.  There  may  be  some 
doubt  as  to  the  correctness  of  the  generic  assignment  of  this  species. 

Nothopus  Lee. 

Notwithstanding  the  evidently  different  facies  of  this  genus  when 
compared  with  the  preceding,  there  is  a  very  close  bond  of  affinity 
and  they  form  a  notably  isolated  group  of  the  Harpalinse,  having  a 
massive  compact  body  and  very  coarse  scattered  setigerous  punc- 
tuation of  the  upper  surface.  The  special  characters  relating  to  the 
anterior  tibiae  constitute  the  only  important  structural  difference 


HARPALIK<E  55 

to  be  noted  so  far  as  observed.  In  Nothopus  the  serial  punctures 
of  the  elytra  are  relatively  much  smaller  than  in  Piosoma  and  they 
are  less  numerous,  but  the  setae  borne  by  them  are  similarly  long 
and  bristling;  the  punctures  of  the  pronotum  are  fine.  There  are 
undoubtedly  a  number  of  distinct  species,  those  represented  in  my 
cabinet  being  as  follows: 

Head  notably  large  in  both  sexes,  distinctly  more  than  half  as  wide  as 
the  prothorax.  Body  large  in  size,  very  stout,  oblong-oval,  convex, 
shining,  black  to  rufo-piceous,  the  legs,  under  surface,  antennae  and 
palpi  paler  and  obscure  rufous,  the  labrum  nearly  black;  head  scarcely 
at  all  punctulate,  the  impressions  long,  parallel,  broadly  and  feebly 
impressed,  uneven  and  rugulose,  the  surface  between  them  also 
rugulose  medially;  labrum  large,  feebly  sinuate  medially,  with 
broadly  rounded  angles;  eyes  very  moderate;  antennae  rather  slender, 
compressed,  extending  barely  to  the  middle  of  the  prothorax,  the 
third  joint  but  little  longer  than  the  second  or  fourth;  prothorax 
nearly  twice  as  wide  as  long,  parallel,  almost  equal  in  width  to  the 
elytra  and  compactly  joined  throughout  the  basal  width,  the  humeri 
only  minutely  exposed,  the  sides  straight,  slightly  rounding  anteriorly, 
the  basal  angles  not  rounded  and  feebly  subeverted;  base  broadly, 
feebly  sinuate  in  median  half,  margined  throughout,  the  apex  feebly 
bisinuato-truncate,  the  fine  margin  broadly  interrupted  medially; 
surface  steeply  declivous  at  the  sides  to  the  conspicuous  and  coarse 
marginal  gutter,  which  expands  basally,  the  edge  strongly  re  flexed 
from  apex  to  base;  toward  base  and  apex  throughout  the  width  with 
rather  sparse,  fine  and  very  distinct  punctures;  median  stria  bi- 
abbreviated  but  rather  deeply  impressed  and  distinct;  foveae  ob- 
solescent; elytra  a  third  longer  than  wide,  two  and  two-thirds  times 
as  long  as  the  prothorax,  subparallel,  slightly  swollen  at  the  sides 
near  the  base,  broadly  and  obtusely  ogival  at  apex,  the  sinus  ob- 
solete; basal  margin  straight,  curving  forward  slightly  to  the 
obtusely  dentate  humeri;  striae  fine,  feebly  (cf)  or  more  strongly  ( 9  ) 
impressed,  the  intervals  flat  to  feebly  convex,  barely  more  convex 
behind,  the  scutellar  stria  long,  the  first  symmetrically  bifurcating 
basally,  as  in  all  the  subsequent  species;  punctures  of  intervals 
3~5~7  very  moderate,  inconstant,  widely  and  unevenly  spaced; 
intervals  4—6—8  also  serially  punctate  toward  apex  as  a  rule;  marginal 
series  uninterrupted  and  irregular;  legs  moderately  long  and  stout, 
the  first  four  joints  of  the  hind  tarsi  decreasing  slowly  and  evenly  in 
length,  the  claws  very  slender  and  strongly  arcuate.  Length  (cf  9  ) 
12.0—15.8  mm.;  width  6.4—7.7  rnm.  Iowa  (Keokuk)  and  Lake

2 — Elytra  barely  perceptibly  longer  than  wide,  the  punctures  of  the 
alternate  intervals  larger,  more  impressed,  more  numerous  and  less

the  coarse  lateral  gutter  expands  much  less  basally;  elytra  similar  in 
structure  but  barely  a  fifth  longer  than  wide  and  more  abruptly  and 
broadly  obtuse  at  apex,  differing  in  the  very  strongly  impressed 
striae  and  notably  convex  intervals,  the  large  impressed  punctures 
very  much  more  numerous,  generally  confused  over  the  entire  width 
of  the  third  interval  posteriorly,  the  punctures  of  the  even  intervals 
few  in  number  and  often  wanting;  tarsi  of  the  female  a  little  more 
slender  than  in  the  male  as  usual.  Length  (cf  9  )  11.8-12.8  mm.;

smaller,  the  labrum  generally  blackish;  prothorax  nearly  as  in 
obtusus;  elytra  a  third  longer  than  wide,  the  striae  fine  and  usually 
feebly  impressed,  the  punctures  of  the  alternate  intervals  small, 
rather  regularly  serial  but  very  widely  and  unevenly  spaced.  Length

in  apical  third,  on  the  fifth  three  or  four  in  apical  third  only,

HARPALIN^:  57 

It  is  often  difficult  to  distinguish  the  male  from  the  female,  but 
in  the  latter  the  hind  tarsi  seem  to  be  a  little  more  slender,  with  the 
fourth  joint  more  elongate  than  in  the  male.  I  should  have  been 
disposed  to  consider  valens  as  identical  with  the  Amara?  grossa  of 
Say,  the  size  and  general  characters  being  similar,  were  it  not  for 
some  irreconcilable  statements  in  the  description  of  that  species, 
which  was  founded  upon  a  single  headless  individual.  Say  states 
that  the  dorsal  line  of  the  prothorax  is  almost  obsolete  in  grossa, 
the  basal  margin  "somewhat  rough"  and  "elytra  with  a  sinus 
near  the  tip."  The  medial  pronotal  stria  is  rather  deeply  impressed 
and  the  surface  basally  and  apically  strewn  with  very  distinct  and 
clearly  isolated  punctures  in  all  the  known  species,  but  the  language 
in  reference  to  the  elytral  sinus  could  not  by  any  seeming  possibility 
apply  to  any  species  described  above,  the  sinus  being  obsolete  and 
traceable  as  a  feebly  straightened  part  of  the  edge  only  under  very 
careful  observation.  It  may  of  course  be  possible  that  the  language 
of  Say  is  inaccurate  and  misleading  and  that  valens  is  really  Amara 
grossa  Say,  as  thought  by  Blatchley,  but  I  do  not  feel  warranted  in 
making  any  such  definite  identification  under  the  circumstances. 

Cratacanthus  Dej. 

It  is  rather  remarkable  to  find  in  a  group  characterized  generally 
by  a  completely  edentate  mentum,  a  genus  in  which  the  mentum 
is  not  only  dentate  but  to  such  an  extreme  degree  as  in  Cratacanthus, 
the  tooth  being  very  acute  and  extending  to  the  transverse  line 
limiting  the  mentum  anteriorly.  The  body  is  nearly  as  in  Crato- 
gnathus  in  its  general  form,  shining  surface  and  freedom  from  sculp- 
ture, but  here  it  is  generally  stouter  in  outline.  The  head  is  rather 
large,  sometimes  very  large,  the  eyes  moderate,  the  antennae  rather 
stout  but  less  so  than  in  Daptus  and  the  third  joint  is  only  a  little 
longer  than  the  second  or  fourth,  the  frontal  impressions  small  and 
punctiform.  The  ligula  is  rather  narrow,  parallel,  not  enlarged 
at  apex,  free  and  exactly  equal  in  length  to  the  paraglossae,  which 
are  very  thick,  pale,  with  triangular  cross-section  apically  and 
obliquely  ciliate  externally  at  tip.  The  prosternal  process  is  un- 
usually broad  and  but  very  little  constricted  by  the  coxae.  The 
prothorax  is  cordiform,  transverse,  with  sharply  marked  right  and 
sometimes  acute  and  slightly  everted  basal  angles,  the  base  strongly 


58  MEMOIRS  ON  THE  COLEOPTERA 

margined  throughout;  the  marginal  gutter  at  the  sides  is  very  deep 
and  equal  from  apex  to  base,  not  expanding  or  becoming  shallower 
toward  base,  a  very  peculiar  character  of  the  genus;  the  elytra  are 
short,  oblong-oval,  not  or  but  little  wider  than  the  prothorax, 
rather  coarsely  and  very  deeply  striate,  with  strong  scutellar  stria, 
which  is  free  and  not  united  with  the  first  stria  and  the  surface  is 
completely  devoid  even  of  the  single  posterior  puncture  of  Crato- 
gnathus;  the  apical  sinus,  so  universal  in  most  of  the  Harpalinae,  is 
completely  obsolete,  not  even  a  vestige  remaining;  the  marginal 
line  of  fovese  is  irregular  and  uninterrupted.  The  legs  are  rather 
short,  the  femora  slightly  swollen,  the  tibiae  slender  and  the  tarsi 
rather  short,  filiform  and  virtually  similar  in  the  sexes,  the  basal 
joint  of  the  posterior  a  little  longer  than  the  second.  The  claws 
are  only  moderate  in  length,  arcuate  and  slender,  though  gradually 
somewhat  thickened  basally.  The  male  has  the  elytra  but  little 
longer  than  the  head  and  prothorax  combined  in  dubius,  but  in  the 
female  they  are  distinctly  less  abbreviated. 

The  species  are  closely  allied  among  themselves  and  subject  to  a 
good  deal  of  variation  in  breadth  of  the  body  and  relative  width 
of  the  anterior  parts  and  elytra,  but  at  the  same  time  four  seem  to 
be  differentiable  in  the  material  at  hand;  these  are  as  follows: 

Head  moderate  in  size  and  in  both  sexes  much  narrower  than  the  pro- 
thorax • 2 

Head  very  large,  only  a  little  narrower  than  the  prothorax 4 

2 — Elytra  but  little  longer  than  the  head  and  prothorax  combined, 
especially  in  the  male.  Body  oblong,  very  convex,  strongly  shining, 
black  to  piceo-rufous  in  color,  always  dark  red-brown  beneath,  the 
legs,  antennae  and  mouth-parts  rufous;  antennae  not  extending  to  the 
middle  of  the  prothorax,  rather  stout,  compressed,  the  joints  rapidly 
narrowed  toward  their  bases;  prothorax  one-half  widep  than  long, 
sinuously  narrowed  basally,  the  base  broadly  and  feebly  sinuate 
except  at  the  sides,  the  apex  subtruncate,  finely  margined  near  the 
sides;  surface  smooth,  with  fine  distinct  biabbreviated  median  line 
and  completely  obsolete  transverse  impressions,  not  at  all  flattened 
postero-externally  and  without  distinct  foveae,  but  densely  and 
rather  coarsely  punctured  in  small  basal  patches  corresponding  to

similarly  very  obtusely  rounded  at  apex;  head  similar  but  with  the 
antennae  more  slender;  prothorax  nearly  similar  and  about  as  wide 
as  the  elytra,  though  with  the  base  not  broadly  sinuate  medially 
but  transverse  and  perfectly  rectilinear  throughout,  the  coarsely 
punctate  basal  foveae  more  pronounced;  elytra  nearly  one-half 
longer  than  wide,  the  striae  less  deeply  impressed  and  sometimes

right  and  not  at  all  everted;  surface  almost  as  in  the  preceding; 
elytra  more  oval,  widest  near  the  middle,  the  apex  more  gradually 
ogival  from  slightly  behind  the  middle;  sides  broadly  arcuate;

four-fifths  as  wide  as  the  prothorax,  the  eyes  a  little  larger  than  usual, 
the  antennae  stout;  prothorax  somewhat  more  than  one-half  wider

The  example  of  dubius  having  the  greatest  width  in  the  measure- 
ments given  above,  is  an  exceptionally  broad  male  from  El  Paso, 
Texas;  the  next  broadest  examples  of  a  large  series  measure  barely 
3.8  mm.  in  width. 

The  names  bisectus  and  litoreus  were  applied  by  the  writer  (Cont. 
Descr.  and  Syst.  Col.  N.  A.,  Pt.  II,  p.  74)  to  very  small  and  odd 
looking  examples  of  the  two  sexes;  not  having  others  to  corroborate 
them,  even  as  subspecies,  the  best  course  is  to  suppress  them  as 
slight  abnormalities.

Glanodes  n.  gen. 

The  type  of  this  genus  is  Har pains  obliquus  Horn.  Dr.  Horn 
does  not  mention  any  dilation  of  the  anterior  male  tarsi  and  repre- 
sentatives of  the  three  species  in  my  collection  betray  no  indication 
of  it,  although  one  of  the  types  seems  to  be  a  male.  The  body  is 
completely  isolated  in  habitus  among  our  Harpalina;,  but  the 
genus  would  seem  to  be  better  placed  at  the  end  of  the  Daptini 
than  anywhere  else;  the  only  other  course  would  be  to  propose  for 
it  a  distinct  tribe.  The  mentum  is  completely  edentate,  the  ligula 
slender,  not  dilated  at  the  bisetose  apex  and  much  shorter  than  the 
paraglossse,  which  are  concave,  only  moderately  broad  and  thick- 
ened and  obliquely  truncate  at  apex;  they  have  two  or  three  short 
external  setae.  The  palpi  are  all  very  slender,  the  second  joint 
of  the  labial  equal  in  length  to  the  third  and  with  about  four  short 
erect  setae.  The  eyes  and  other  dorsal  cephalic  characters  are 
exactly  as  in  Cratacanthus ,  but  the  antennae  are  less  abbreviated. 
The  prothorax  is  distinctly  wider  than  the  head,  with  strongly 
oblique  straight  sides  posteriorly,  the  surface  smooth  and  convex, 
steeply  and  evenly  declivous  at  the  sides  to  the  very  finely  reflexed 
margin  throughout,  the  fovese  usually  deep;  the  base  is  margined. 
The  elytra  are  oval,  finely  striate,  with  or  without  a  dorsal  setigerous 
puncture,  the  punctures  and  foveae  of  the  marginal  interval  small, 
diffused  and  uninterrupted;  the  scutellar  stria  is  fine,  rather  short, 
free  and  oblique.  The  intercoxal  process  of  the  prosternum  is 
broad,  but  feebly  constricted  by  the  coxae  and  as  usual  plurisetose. 
The  hind  tarsi  are  slender,  with  the  first  four  joints  decreasing  slowly 
and  evenly  in  length,  the  first  much  shorter  than  the  fifth;  the 
claws  are  arcuate,  extremely  slender  and  moderate  in  length.  We 
appear  to  have  four  species  as  follows: 

Elytra  with  a  small  setigerous  puncture,  externally  adjoining  the  second 

stria  near  apical  third 2 

Elytra  without  trace  of  a  dorsal  setigerous  puncture  near  the  stria.  .  .  .3 
2 — Legs  and  antennae  ferruginous.  Pitchy  black,  shining;  head  moder- 
ate, sparsely  punctate;  prothorax  cordate,  one-third  wider  than  long, 
the  sides  in  front  arcuate,  posteriorly  oblique,  the  margin  very 
narrow;  base  narrower  than  the  apex;  hind  angles  not  prominent, 
very  obtuse,  the  point  of  the  angle  blunt;  basal  angular  impressions 
moderately  deep,  somewhat  triangular  and  punctured,  the  median 
line  distinctly  impressed,  the  surface  moderately  convex  shining, 
with  a  few  punctures  along  the  basal  margin;  elytra  oval,  the  humeri

obtusely  rounded,  the  apex  feebly  sinuate;  surface  striate,  the  striae 
impunctate,  the  intervals  slightly  convex,  with  a  single  dorsal 
puncture,  which  is  at  posterior  third  on  the  third  interval  near  the 
second  stria;  under  surface  pitchy  black,  smooth,  the  abdomen  with 
a  few  punctures  near  the  base  and  at  the  sides  bearing  accessory  setae; 
mentum  without  tooth.  Length  10.0  mm.  New  Mexico  (Fort 
Bayard).  [Harpalus  obliquus  Horn] obliquus  Horn 

Legs  piceous-black,  the  antennae  obscure  rufous.  Black  and  shining 
above,  piceous-black  beneath,  the  abdomen  slightly  rufescent;  head 
with  small  impressed  punctures  loosely  and  evenly  distributed  over 
the  entire  surface,  two-thirds  as  wide  as  the  prothorax,  the  mandibles 
stout,  strigose,  the  eyes  moderate,  the  antennae  not  extending  to  the 
thoracic  base;  prothorax  one-half  wider  than  long,  the  sides  rounded 
anteriorly,  very  oblique  and  straight  thence  to  the  base,  which  is 
broadly  and  very  feebly  sinuate  throughout  and  barely  more  than 
two-thirds  the  maximum  width,  the  apex  sinuato-truncate,  with  the 
angles  rounded;  basal  angles  very  obtuse,  blunt  though  barely  at  all 
rounded;  surface  convex,  smooth,  very  shining,  with  some  very  fine 
sparse  punctulation  basally,  the  foveae  deep,  a  sixth  the  total  length, 
linear,  punctate  and  separated  from  the  sides  by  a  convex  surface; 
elytra  oval,  subalutaceous,  one-half  longer  than  wide,  a  third  wider 
than  the  prothorax  and  less  than  three  times  as  long,  very  obtuse  at 
apex,  the  sides  roynded,  the  sinus  broad  and  barely  traceable,  obso- 
lete; striae  fine,  the  scutellar  oblique,  the  intervals  flat,  the  dorsal  punc- 
ture small,  at  posterior  third;  intervals  3-5-7  with  two  to  four  small 
punctures  forming  even  medial  series  near  the  apex;  lateral  foveae 
very  small,  widely  separated  throughout,  with  a  few  smaller  and 
sparser  punctures  intermingled;  abdomen  punctulate  basally  and 
with  numerous  accessory  setae;  first  three  joints  of  the  hind  tarsi 
subequal  and  much  shorter  than  the  fifth.  Length  (9  )  10.5  mm.; 
width  3.8  mm.  Arizona  (Peach  Spring), — Wickham.

when  compared  with  the  elytra  than  in  the  next  species;  deep  black, 
shining,  the  elytra  less  alutaceous  than  in  puncticeps,  the  under 
surface  and  legs  piceo-rufous,  the  antennae  and  mouth  parts  fer- 
ruginous; head  not  quite  so  large  and  with  somewhat  smaller  eyes 
than  in  the  preceding,  the  surface  with  fine  sparse  punctures,  evenly 
disposed  throughout  but  much  more  obsolete  than  in  puncticeps; 
prothorax  similar  in  form  but  with  the  base  transverse  and  recti- 
linear throughout  and  with  the  very  obtuse  angles  sharply  marked 
and  not  blunt  at  tip,  though  not  at  all  prominent;  surface  nearly 
similar,  the  side  margin  a  little  less  fine  and  similarly  disappearing— 
with  the  exception  of  the  marginal  bead — near  the  hind  angles,  the 
median  stria  also  strong,  not  attaining  base  or  apex,  the  scattered 
basal  punctures  extremely  minute,  obsolescent  medially,  the  foveae 
sublinear  but  broadly  and  very  feebly  impressed  and  subobsolete, 
finely  punctulate;  elytra  oblong-oval,  the  humeri  rather  less  broadly 
rounded  than  in  the  preceding,  the  apical  sinus  rather  more  obvious, 
the  striae  fine  but  more  impressed,  the  scutellar  still  shorter  and

finer,  oblique,  the  intervals  feebly  convex,  the  punctures  of  3-5-7 
only  two  to  three  in  number  and  still  more  apical,  the  lateral  foveae 
and  scattered  punctures  stronger;  tarsi  nearly  similar  but  a  little 
shorter.  Length  ( 9  )  9-O  mm.;  width  3.7  mm.  Utah  (Virgin  River). 

corpulentus  n.  sp. 

Form  more  parallel,  probably  by  reason  of  sexuality  to  some  extent,  the 
anterior  parts  much  larger  when  compared  with  the  elytra  than  in 
the  types  of  the  three  preceding,  somewhat  piceous  black  above,  the 
under  surface  piceo-ferruginous,  the  legs  paler  and  more  yellow, 
the  antennae  and  mouth  parts  as  usual;  head  nearly  three-fourths 
as  wide  as  the  prothorax,  the  punctulation  similar  but  still  finer, 
sparser  and  nearly  obsolete,  the  antennae  about  attaining  the  thora- 
cic base;  prothorax  barely  two-fifths  wider  than  long,  nearly  similar 
in  general  form  but  with  the  transversely  rectilinear  base  just 
visibly  sinuate  opposite  each  fovea  and  with  the  obtuse  angles  nar- 
rowly rounded;  surface  with  a  few  longitudinal  wrinkles  anteriorly 
and  medio-basally,  the  foveae  short,  very  deep,  punctulate,  broaden-

extending  some  distance  from  the  apex  as  in  pitncticeps,  the  marginal 
punctures  and  foveae  small  and  sparse;  hind  tarsi  with  the  first  four 
joints  decreasing  uniformly  and  rather  rapidly  in  length,  the  anterior 
much  shorter  than  the  others  but  slender,  nude  beneath.  Length 
(cf)  9.0  mm.;  width  3.4  mm.  Arizona  (near  Benson), — Dunn. 

regressus  n.  sp. 

Either  the  figure  of  obliquus  given  by  Horn  is  erroneous — as  is 
probably  true — or  that  species  differs  distinctly  from  any  at  hand 
also  in  the  punctuation  of  the  head,  for,  as  drawn,  the  punctures 
are  mainly  limited  to  a  triangular  median  part,  instead  of  being 
evenly  diffused  throughout  as  in  all  the  others.  It  is  also  probable 
that  the  author  neglected  to  observe  the  punctures  near  the  apices 
of  intervals  3-5-7  on  the  elytra,  which,  without  much  doubt,  are 
present  in  his  type  of  obliquus.  These  punctures  indicate  some 
affinity  with  Piosoma  alternata,  as  is  also  the  case  with  Cratognathus 
cordatus  Lee.,  of  the  Harpalini,  referred  below  to  a  separate  genus. 
These  punctures  also  reappear  in  many  Anisodactylids,  forming 
thus  another  case  of  parallelism  of  development  or  reversion. 

Tribe  HARPALINI. 

This  tribe  is  the  largest  of  the  subfamily  and  probably  the  most 
difficult,  so  far  as  the  delimitation  of  genera  is  concerned.  It  was 


HARPALIN^E  63 

the  opinion  of  Dr.  Horn  that  the  organs  of  the  mouth  were  of  less 
weight  in  the  classification  of  the  genera  of  Carabidse  than  they 
had  been  held  to  have,  and  this  is  probably  true  generally,  but  in 
this  particular  tribe  I  find  them  to  be  decidedly  useful ;  the  dentition 
of  the  mentum  however,  here,  as  well  as  in  the  Anisodactylini, 
loses  much  of  the  value  that  it  possesses  elsewhere  and  more  especi- 
ally in  the  large  tribe  of  very  small  species,  known  as  the  Acupalpini. 
In  the  subjoined  table,  many  of  the  foreign  genera  are  omitted 
because  of  lack  of  material,  but  so  far  as  represented  in  my  col- 
lection they  may  be  arranged  as  follows: 

Basal  joint  of  the  hind  tarsi  seldom  much  elongated,  more  or  less  evi- 
dently shorter  than  the  next  two  combined;  elytra  never  opalescent, 
though  sometimes  metallic 2 

Basal  joint  much  elongated,  equal  to  or  exceeding  the  next  two  combined, 
the  elytra  always  having  strong  prismatic  iridescence  as  in  many  of 
the  Selenophorini 10 

2 — Paraglossae  diverging  apically,  more  or  less  narrowly  rounded  at  tip 
and  much  longer  than  the  ligula 3 

Paraglossae  more  rounded,  generally  broadly  rounded  and  thickened  at 
apex,  more  or  less  nearly  equal  in  length  to  the  ligula;  alternate  elytral 
intervals  rarely  with  serial  punctures  at  apex,  the  only  instances 
observed  being  on  7  or  5  and  7  in  certain  Acinopus  and  Artabas .  .  .5 

3 — Elytra  with  serial  punctures  on  intervals  3-5-7  toward  apex,  as  in 
Glanodes  of  the  preceding  tribe;  body  Cratacanthus-like  in  habitus, 
the  prothorax  cordiform,  with  right  and  sharply  marked  basal  angles. 
Sonoran  regions Opadius 

Elytra  without  trace  of  serial  punctures  on  intervals  3-5-7 4 

4 — Body  Cratacanth its-like  in  habitus,  compact,  oblong,  the  hind  angles 
of  the  prothorax  sharply  rectangular;  integuments  very  pallid  in 
coloration  but  thick  and  solid  as  in  Geopinus;  mentum  tooth  want- 
ing or  vestigial,  the  elytra  without  a  dorsal  setigerous  puncture. 
Gulf  regions Pharalus 

Body  with  a  somewhat  Acinopus-like  facies  but  very  small  in  size,  the 
basal  thoracic  angles  broadly  rounded;  integuments  dense,  black 
as  usual;  second  labio-palpal  joint  longer  and  relatively  thinner  than 
in  any  other  genus  of  the  tribe;  head  very  large;  mentum  edentate. 
South  Africa *Micracinopus 

5 — Anterior  and  middle  tarsi  subequally  dilated  in  both  sexes  but  bi- 
seriately  squamose  beneath  only  in  the  male  as  usual;  second  joint 
of  the  labial  palpi  much  longer  than  the  third;  mandibles  stout  and 
strigose;  basal  thoracic  angles  broadly  rounded;  head  large;  mentum 
edentate.  Palaearctic  regions 6 

Anterior  and  middle  tarsi  dilated  much  more  strongly  in  the  male,  where 
they  are  biseriately  squamose  beneath 7

body  broad  and  of  large  size,  the  tarsi  all  very  stout;  marginal  stiia

habitus,  smooth  to  distinctly  punctate  in  various  parts,  in  one  or 
both  sexes,  but  never  having  the  pronotum  coarsely  punctured 
throughout  as  in  the  Dicheirus-like  Ophonus;  mentum  dentate  to 
edentate;  second  labio-palpal  joint  a  little  longer  than  the  third.

unusually  slender  and  barely  at  all  compressed.  South  Africa.

10 — Elytra  with  a  single  subposterior  dorsal  puncture,  always  strongly 
opalescent;  ligula  as  long  as  the  paraglossae  or  nearly  so,  rather  wide, 
distinctly  expanded  at  tip,  the  paraglossae  of  peculiar  form,  narrowly 
prolonged  externally  at  apex;  labial  palpi  slender,  gradually  acu- 
minate at  tip,  the  second  and  third  joints  equal  in  length;  mentum 
toothed.  North  America,  excepting  the  Pacific  regions.  .Pteropalus 

The  few  exotic  genera  are  introduced  merely  for  comparison 
with  our  own  and  can  be  disposed  of  in  few  words  at  this  time. 

MICRACINOPUS  n.  gen. — The  type  of  this  genus  is  a  very  small 
species  which  I  took  at  Wellington,  near  Cape  Town;  it  may  be 
described  briefly  as  follows: 

*Micracinopus  politissimus  n.  sp. — Narrowly  oblong-suboval,  convex, 
polished,  black  above  and  beneath,  the  elytra  with  just  visible  bluish 
lustre,  the  epipleura  piceous;  legs,  palpi  and  antennae  pale  testaceous- 
yellow;  head  but  very  little  narrower  than  the  prothorax,  the  eyes  rather 
large  but  only  moderately  convex,  the  mandibles  stout  and  the  frontal 
impressions  small  and  punctiform;  prothorax  transverse,  three-fourths 
wider  than  long,  the  sides  broadly  rounded,  gradually  slightly  converging 
and  becoming  not  quite  straight  to  the  very  broadly  rounded  basal  angles, 
the  base  transverse  and  margined  throughout,  not  quite  as  wide  as  the 
feebly  sinuato-truncate  apex;  surface  smooth,  steeply  sloping  laterally  to 
the  very  fine  re  flexed  margin,  the  foveae  narrow,  short  and  sublinear,  deep 
and  obscurely  punctate,  the  surface  thence  to  the  angles  more  feebly 


HARPALIN.E  65 

convex  and  punctureless,  the  median  stria  distinct;  elytra  rather  less 
than  one-half  longer  than  wide,  a  little  wider  than  the  prothorax,  the 
sides  parallel  and  feebly  arcuate,  the  apex  obtusely  ogival,  the  sinus  very 
feeble;  striae  rather  fine  but  impressed,  deeply  so  toward  suture  and  tip, 
where  the  intervals  become  more  convex,  the  scutellar  short,  fine  and 
oblique;  dorsal  puncture  wanting,  the  lateral  line  of  fovese  inter- 
rupted medially;  anterior  and  middle  tarsi  (d71)  rather  strongly  dilated 
and  biseriately  squamose.  Length  (cf )  7.3  mm.;  width  2.7  mm.  South 
Africa. 

It  is  of  course  quite  possible  that  this  species  may  already  be 
described  under  another  name,  but  I  have  been  unable  to  find  any 
reference  to  it. 

OSIMUS  Mots. — There  are  many  characters  in  the  type  and  only 
species  of  this  genus,  the  Acinopus  ammophilus  of  Dejean,  such  as 
the  broad  and  Zabrus-\ike  form  of  the  body,  very  stout  tibial  spurs, 
form  of  the  head  and  long  vestiture  of  the  abdomen,  which  would 
seem  to  validate  Osimus  as  a  genus,  rather  than  a  subgenus  of 
Acinopus,  where  it  now  rests;  but  my  unfamiliarity  with  most  of 
the  true  Acinopi  gives  to  these  assumptions  but  little  value. 

ACINOPUS  Dej. — The  assumed  type  of  this  genus,  in  comparisons 
which  I  have  made  with  the  preceding,  is  the  species  at  present 
listed  as  picipes  Oliv.  The  body  is  of  a  peculiar  compact,  parallel, 
convex  and  cylindric  form,  distinguishing  it  at  once,  not  only  from 
any  Harpalus,  but  quite  as  distinctly  from  Osimus.  The  genus 
Acinopus  appears  to  be  peculiar  to  the  palaearctic  faunal  regions. 

OPHONUS  Steph. — This  genus  was  not  considered  to  be  distinct 
from  Harpalus  by  Lacordaire,  though  so  esteemed  by  modern 
European  writers.  In  so  far  as  the  species  before  me,  azureus

the  recent  catalogue  of  Heyden,  Reitter  and  Weise,  some  other 
elements  are  incorporated  with  Ophonus  which  do  not  belong  there, 
such  for  example  as  Harpalophonus  Gangl.,  founded  upon  such  forms 
as  hospes;  this  is  undoubtedly  a  Harpalus,  in  its  broad  sense,  and 
has  very  little  affinity  with  Ophonus  azureus. 

RAPHALUS  n.  gen. — The  type  of  this  genus,  which  is  close  to 
Harpalus,  may  be  defined  as  follows: 

*Raphalus  convergens  n.  sp. — Body  oblong,  moderately  convex, 
strongly  shining,  black,  the  under  surface  more  piceous,  the  legs,  antennae 
and  trophi  pale  testaceous;  head  fully  two-thirds  as  wide  as  the  prothorax, 
slightly  constricted  behind  the  prominent  eyes,  the  front  very  smooth, 
with  excessively  fine  straight  epistomal  suture,  behind  which  the  foveaa

take  the  form  of  extremely  small  punctures,  the  oblique  lateral  part  of 
the  suture  obsolete;  antennae  extending  fully  to  the  thoracic  base,  very 
slender,  the  third  joint  but  little  longer  than  the  fourth  but  much  longer 
than  the  second;  prothorax  one-half  wider  than  long,  the  sides  evenly 
rounded,  becoming  oblique  and  broadly  sinuate  basally,  the  base  feebly 
sinuate,  except  laterally,  very  finely  margined,  the  angles  slightly 
obtuse  but  not  evidently  rounded;  surface  feebly  convex,  smooth,  broadly 
and  feebly  impressed  near  each  side  basally,  the  impressions  with  a  few 
punctures;  median  stria  fine,  extending  only  to  the  obsolete  anterior 
transverse  impression,  the  side  margins  rather  finely  reflexed  and  sub- 
equally  so  throughout  to  the  basal  angles;  elytra  oblong-oval,  with  parallel 
and  broadly  arcuate  sides,  one-half  longer  than  wide,  a  fifth  wider  than 
the  prothorax,  obtusely  ogival  at  tip,  with  broad  and  feeble  oblique 
sinus;  striae  rather  fine  and  slightly  impressed,  the  scutellar  free,  moderate, 
oblique,  the  second  with  a  discal  puncture  externally  attached  at  apical 
fourth;  lateral  foveae  widely  spaced  medially;  abdomen  not  punctulate; 
anterior  and  middle  tarsi  (cf)  dilated  and  biseriately  squamose  beneath, 
the  posterior  slender,  with  the  first  four  joints  gradually  diminishing  in 
length,  the  first  equal  in  length  to  the  fifth.  Length  (cf)  9-2  mm.; 
width  2.5  mm.  South  Africa  (Cape  Town). 

I  am  by  no  means  certain  that  this  species  may  not  have  been 
previously  described,  but  can  find  no  definite  reference.  If  de- 
scribed, it  can  be  recognized  readily  from  the  description.  I  took 
the  single  representative  not  far  from  the  town  more  than  thirty 
years  ago. 

The  presence  or  absence  of  so-called  opalescent  lustre  of  the 
integuments  is  nearly  always  an  important  character,  usually  in 
fact  generic  in  significance,  for  this  play  of  prismatic  color  is  due  to 
an  exceedingly  minute  strigilation,  forming  a  true  diffraction 
grating,  such  as  is  used  for  the  formation  of  a  light  spectrum,  while 
the  absence  of  opalescence  indicates  that  the  minute  sculpture  is 
of  an  entirely  different  order,  taking  the  form  of  reticulation,  when 
sculpture  of  any  kind  is  present. 

Opadius  n.  gen. 

The  type  of  this  genus  was  originally  described  by  LeConte 
under  the  name  Cratognathus  cordatus  and  was  compared  with 
Piosoma,  with  which  it  may  have  somewhat  more  than  a  super- 
ficial affinity,  owing  to  the  well  developed  alternating  series  of 
interstitial  punctures,  only  visibly  however  toward  apex,  together 
with  a  generally  compact  convex  form  of  body  and  Cratacanthus- 
like  prothorax.  It  was  subsequently  referred  by  Horn  and  LeConte 


HARPALIISLE  67 

to  Harpalus,  because  of  the  distinctly  dilated  and  squamulose 
male  tarsi.  There  can  be  hardly  a  doubt  that  it  represents  a  dis- 
tinct genus  however,  which  is  proposed  under  the  above  name. 
The  single  known  species  is  the  following: 

Body  stout,  oblong  and  convex,  shining,  dark  rufo-piceous,  the  under 
surface  and  legs  a  little  paler;  antennae  and  trophi  testaceous;  head 
three-fourths  as  wide  as  the  prothorax,  with  prominent  and  moderate 
eyes;  antennae  rather  slender,  extending  well  behind  the  thoracic 
base,  the  third  joint  distinctly  longer  than  the  second  or  fourth; 
mandibles  short  and  stout,  flattened  above,  feebly  strigose  apically, 
the  left  with  a  finely  incurved  point  at  apex,  the  right  simply  obliquely 
acute  at  tip;  frontal  foveae  short,  irregularly  impressed;  prothorax 
between  a  third  and  fourth  wider  than  long,  broadly  rounded  at  the 
sides,  sinuately  narrowing  basally,  the  angles  right  and  sharply 
marked;  base  transverse,  as  wide  as  the  apex,  feebly  bisinuate, 
finely  margined;  surface  convex,  with  fine  diffused  punctures  latero- 
basally,  the  median  stria  distinct,  the  foveae  short,  rather  deeply 
impressed,  the  side  margins  finely  reflexed  and  equally  so  to  the 
basal  angles,  being  separated  from  the  foveae  at  base  by  a  convexity 
as  in  Cratacanthus  and  Glanodes;  elytra  short,  oblong-oval,  evidently 
wider  than  the  prothorax  and  two-fifths  longer  than  wide,  very 
obtuse  at  apex,  the  sinus  indistinct,  vestigial;  sides  broadly  arcuate; 
striae  fine  but  rather  well  impressed,  with  a  setigerous  puncture  just 
outside  the  second  before  apical  third,  the  scutellar  stria  rather  short; 
marginal  punctures  irregular,  subinterrupted  medially;  basal  joint 
of  the  hind  tarsi  barely  longer  than  the  second,  evidently  shorter  than 
the  fifth;  abdomen  with  basal  punctulation  and  some  accessory  setae 
as  in  Glanodes  and  many  Harpali.  Length  (cf1)  7.3-7.5  mm.; 
width  2.8-2.9  mm-  Arizona  (southern).  [Cratognathus  cordatus 
Lee.] cordatus  Lee. 

The  affinity  of  this  species  with  the  Harpalus  obliquus  of  Horn, 
has  been  pointed  out  by  that  author  under  his  description  of  the 
latter,  which  is  here  referred  to  the  Daptini,  especially  because 
there  is  no  evidence  at  hand  that  the  anterior  tarsi  of  the  male  are 
dilated  and  squamose.  Perhaps,  however,  I  may  have  mistaken 
the  sex  of  the  type  of  Glanodes  regressus;  it  is  quite  different  in 
general  form  from  the  types  of  the  other  species,  owing  to  the 
relatively  larger  head  and  prothorax,  and,  as  those  types  are  un- 
equivocally female,  it  is  assumed  that  the  type  of  regressus  is  a  male. 
However,  even  though  the  anterior  male  tarsi  of  Glanodes  should 
prove  to  be  harpaliform,  it  cannot  be  congeneric  with  Opadius 
cordatus,  though  in  such  case  to  be  placed  near  the  present  genus 
in  the  Harpalini,  instead  of  in  its  present  place  at  the  end  of  the

Daptini,  with  which  tribe  it  confessedly  does  not  harmonize  very 
well  in  facies. 

Pharalus  n.  gen. 

In  this  genus  the  habitus  is  peculiar,  but  more  remindful  of 
Cratacanthus  than  of  Harpalus,  where  it  now  rests  in  our  lists; 
the  type  was  originally  described  by  LeConte  under  the  name 
Pangus  testaceus,  because  of  the  absence  of  a  mentum  tooth;  the 
tooth  may  however  be  wholly  wanting  or  present  in  the  form  of  a 
short  though  decided  arcuate  projection,  being  thus  variable  in- 
dividually. The  humeri  are  sharply  denticulate.  The  only  known 
species  may  be  described  as  follows : 

Body  oblong,  stout,  parallel,  strongly  convex,  very  shining  throughout 
and  pale  testaceous-yellow  in  color,  without  darker  shading  of  any 
sort,  the  elytra  highly  polished  in  both  sexes;  head  three-fifths  as 
wide  as  the  prothorax,  with  large  and  prominent  eyes,  the  antennae 
stout,  not  quite  extending  to  the  thoracic  base;  mandibles  stout, 
the  left  much,  the  right  scarcely  at  all,  produced  inward  at  apex; 
frontal  foveae  small,  sharply  defined  and  deep;  prothorax  three-fifths 
wider  than  long,  the  sides  broadly  and  feebly  rounded,  slightly  con- 
verging and  broadly,  barely  visibly  sinuate  posteriorly,  the  angles 
right  and  very  sharp;  base  strongly  margined,  feebly  sinuate- 
truncate,  a  little  wider  than  the  apex,  which  is  broadly  sinuate, 
with  widely  rounded  angles;  surface  broadly  convex,  smooth,  the 
side  margins  rather  coarsely  reflexed,  more  broadly  so  and  deplanate 
basally,  sparsely  punctured  throughout,  the  foveae  short,  sublinear, 
deeply  impressed  and  punctate,  separated  from  the  deplanate 
angles  by  a  smooth  convex  surface;  median  stria  fine  but  evident 
except  apically;  elytra  oblong,  fully  one-half  longer  than  wide,  very 
little  wider  than  the  prothorax,  obtuse  at  apex,  the  sinus  vestigial, 
subrectilinear;  striae  not  coarse  but  very  deeply  impressed,  the  scu- 
tellar  long  and  strong,  joining  the  first;  lateral  foveae  small,  the  dorsal 
completely  wanting;  anterior  and  middle  tarsi  (cf )  well  dilated  and 
inferiorly  squamose,  the  posterior  slender,  with  the  first  four  joints 
decreasing  very  slowly,  the  first  much  shorter  than  the  fifth.  Length 
(o71  9  )  9.8-10.7  mm.;  width  3.8-4.3  mm.  Illinois,  Iowa  and  Mis- 
souri. [Pangus  testaceus  Lee.] testaceus  Lee. 

It  is  very  difficult  to  understand  just  how  to  dispose  of  some  of 
the  so-called  aberrant  Harpalids  of  LeConte  and  Horn,  especially 
those  which  I  have  here  assigned  to  the  genera  Glanodes,  Opadius 
and  Pharalus.  They  all  have  accessory  abdominal  setae,  as  in  the 
fraternus  group  of  Harpalus,  with  which  they  undoubtedly  have  a 
close  affinity,  and  I  have  separated  them  more  because  of  pro-

nounced  peculiarities  of  habitus  than  any  single  structural  character, 
although  in  Pharalus  testaceus  the  ligula  is  abruptly  and  strongly 
dilated  and  very  acutely  angulate  at  each  side  of  the  apex  and  the 
paraglossae  are  produced  externally  at  apex,  leaving  an  internal 
sinus  adjoining  the  ligula,  somewhat  as  in  most  of  the  Selenophorid 
genera. 

Harpalus  Latr. 

This  is  the  largest  genus  of  the  subfamily  and  one  of  the  most 
important  of  the  entire  Carabidae  from  the  standpoint  of  extent, 
and  perhaps  the  most  difficult  in  regard  to  the  taxonomy  of  its 
diversified  elements.  Here  the  mentum  tooth,  because  of  its 
inconstancy,  has  but  little  value  in  classification.  The  body  is 
notably  varied  in  habitus,  due  principally  to  the  presence  or  absence 
of  punctuation  at  various  parts  of  the  surface,  to  the  female  sexual 
characters  on  and  at  the  apices  of  the  elytra,  in  size  and  form  of  the 
body  and  in  other  ways,  so  that  Lacordaire  was  very  undecided 
as  to  its  boundaries,  including  some  named  genera  that  have  since 
been  separated  on  more  or  less  evident  structural  peculiarities. 
The  mentum  is  of  the  usual  short  transverse  form  but  the  apical 
projections,  limiting  the  large  median  sinus,  are  unusually  acute 
and  dentiform.  The  third  joint  of  the  labial  palpi  is  generally  but 
little  shorter  than  the  second. 

Harpalus  is  the  only  genus  of  the  subfamily  that  is  distributed  in 
about  equal  numbers  through  the  palsearctic  and  nearctic  regions. 
In  the  southern  hemisphere  it  is  rather  abundant  in  South  Africa, 
from  which  region  I  personally  collected  four  or  five  species  in  the 
vicinity  of  Cape  Town.  It  is  however  suspected  by  Bates  that 
the  genus  does  not  occur  in  either  South  America  or  Australia. 

In  the  following  table  of  the  groups  into  which  our  very  numerous 
species  may  be  apportioned,  I  have  not  attempted  to  assign  sub- 
generic  names  except  in  a  few  cases,  not  knowing  the  named  groups 
of  the  European  fauna,  with  which  a  number  of  our  own  are  doubt- 
less identical,  and  I  have  furthermore  limited  the  groups  here 
defined  to  our  own  fauna  alone,  not  attempting  to  incorporate  even 
such  as  Artabas  or  Pangus  of  the  European  fauna.  Our  very  iso- 
lated viridi&neus  makes  the  closest  approach  to  Harpalophonus  and 
will  probably  have  to  be  included  therein.

Group  I   (caliginosus) . 
Subgenus  Megapangus  nov. 

There  is  but  a  single  extremely  common  and  widely  diffused 
species  as  follows: 

Body  large  in  size,  elongate-oblong,  moderately  convex,  shining,  black 
above  and  beneath,  the  legs  black,  with  the  anterior  and  middle 
taisi  piceo-rufous,  the  antennae  and  trophi  testaceous;  head  rather 
large,  three-fifths  as  wide  as  the  prothorax,  with  moderately  large 
and  prominent  eyes,  the  frontal  foveae  unusually  large  and  notably 
deep;  prothorax  two-thiids  wider  than  long,  the  base  broadly  and 
feebly  sinuate,  very  imperfectly  margined,  much  wider  than  the 
apex,  the  basal  angles  right  and  very  sharply  marked,  the  sides 
broadly  rounded  and  converging  anteriorly,  the  side  margins 
deplanate,  gradually  very  broadly  so  basally  and  densely  punctured, 
the  foveae  very  large,  feebly  impressed,  vague  and  densely  punctato- 
rugose;  medial  parts  of  the  base  very  sparsely  punctulate;  lateral 
bead  strong  and  abruptly  elevated;  median  stria  very  fine;  there 
are  traces  of  a  feeble  anterior  transverse  impression,  which  is  finely, 
suffusedly  punctulate;  elytra  parallel,  barely  at  all  wider  than  the 
prothorax,  one-half  longer  than  wide,  very  obtusely  ogival  at  apex, 
with  obsolete  and  barely  traceable  sinus,  the  striae  strong,  impressed, 
finely  punctulate  at  the  bottom,  the  scutellar  very  long,  joining  the 
first,  which  therefore  bifurcates  at  base,  the  intervals  smooth,  feebly 
convex,  the  marginal  gutter  rather  wide  and  deep,  the  marginal 
interval  opaque  and  with  fine  suffused  punctures  extending  onto 
the  outer  half  of  the  eighth  interval,  the  line  of  foveae  indistinct 
medially  though  scarcely  interrupted;  abdomen  smooth  and  shining 
medially,  punctured  densely  toward  the  sides  and  with  asperate 
setigerous  punctures  medially  at  base;  first  four  joints  of  the  hind 
tarsi  decreasing  evenly  and  rapidly  in  length,  the  first  longer  than 
the  fifth.  Length  (cf  9  )  17.5-26.0  mm.;  width  6.8-9.7  mm.  Maine 
to  California  and  Texas caliginosus  Fabr. 

LeConte  placed  this  species  in  Pangus  Zieg.,  apparently  solely 
because  of  the  absence  of  the  mentum  tooth.  It  is  a  very  isolated 
species  and  merits  subgeneric  designation  as  proposed  above. 
There  is  but  little  variation  in  this  probably  long  geologically 
established  species,  except  in  size;  one  very  large  female  from 
Illinois,  however,  has  longer  elytra  and  a  noticeably  larger  head 
than  the  average.

Group  II   (er r aliens) . 
Subgenus  Plectralidus  nov. 

The  habitus  in  this  group  is  altogether  isolated  in  the  genus, 
the  body  being  very  elongate  and  rather  large  though  extremely 
variable  in  size  intraspecifically  and  the  coloration  varies  from  a 
peculiarly  pallid  tint  to  deep  black;  the  external  dentition  of  the 
elytral  apices,  which  in  the  female  sometimes  becomes  conspicuously 
spiniform,  is  a  remarkable  and  distinctive  character  of  the  group. 
We  apparently  have  six  species  as  follows: 

Basal  angles  of  the  prothorax  obtuse  and  narrowly  rounded  or  never 
sharply  marked 2 

Basal  angles  sharply  marked,  not  blunt  and  generally  subprominent; 
outer  prominence  at  the  elytral  apices  very  obtuse,  never  spiniform 
even  in  the  female 5

throughout  (cf )  or  with  the  elytra  duller  (9  ),  piceo-rufous  in  color, 
the  elytra  nearly  black;  under  surface,  legs,  antennae  and  trophi 
rufous;  head  rather  large,  three-fourths  as  wide  as  the  prothorax, 
with  prominent  eyes,  the  frontal  foveae  very  small,  lying  in  large, 
feeble  and  very  vague  impressions;  antennae  extending  fully  to  the 
thoracic  base;  prothorax  only  about  a  fourth  or  fifth  wider  than  long, 
the  transverse,  strongly  margined  base  as  wide  as  the  broadly 
sinuate  apex,  the  sides  broadly  and  feebly  arcuate,  becoming  gradu- 
ally slightly  convergent  basally,  the  obtuse  angles  evidently  rounded 
though  distinct;  surface  smooth,  the  side  margins  rather  strongly 
re  flexed,  the  gutter  coarse  and  deep,  punctulate,  much  expanded  into 
the  flattened  and  sparsely  punctured  latero-basal  regions,  the  foveae 
rather  large,  feebly  and  somewhat  vaguely  impressed,  punctulate; 
median  stria  fine;  elytra  long,  three-fourths  longer  than  wide  (c?) 
and  nearly  so  (9  ),  obtuse  at  tip,  the  striae  deeply  impressed,  with 
shining  convex  intervals  and  the  sides  feebly  arcuate  (o71 ),  or  with 
the  striae  feebler,  the  intervals  flatter  and  the  sides  more  arcuate 
(9),  two-fifths  to  one-half  wider  than  the  prothorax;  first  four

as  long  as  the  fifth.  Length  (d71  9)  11.7-16.0  mm.;  width  3.7-5.8

4 — Body  about  as  narrow  and  elongate  as  in  err  aliens  but  much  more 
convex,  extremely  shining  and  sculptureless  throughout  above  in 
the  male  and  deep  black  in  color,  blackish-piceous  beneath,  the  legs 
paler,  rufous;  head  nearly  as  in  erraticus,  the  eyes  not  quite  so 
prominent;  prothorax  a  fourth  wider  than  long,  throughout  nearly 
similar,  except  that  the  reflexed  side  margins  are  a  little  narrower 
and  the  latero-basal  punctures  stronger  as  a  rule,  the  angles  obtuse 
and  narrowly  rounded,  the  sides  more  strongly  converging  basally 
than  in  either  of  the  first  two  species;  elytra  shorter,  two-thirds 
longer  than  wide,  only  about  a  fourth  wider  than  the  prothorax,  the 
striae  similarly  deeply  impressed,  with  strongly  convex  intervals, 
the  scutellar  stria  not  quite  so  long,  not  joining  the  first,  the  apical 
sinus  (cf )  less  broad  and  relatively  deeper  externally,  the  parallel 
sides  more  arcuate  and  with  rather  narrower  reflexed  margins;  tarsi

Body  smaller  and  much  shorter,  more  depressed  and  rather  less  shining, 
only  a  little  larger  in  the  female  than  in  the  male,  the  elytra  (  9  ) 
more  shining  than  in  erraticus  (9  )  and  very  much  more  so  than  in 
the  nearly  opaque  caudalis,  black,  the  under  surface  more  piceous, 
the  legs  pale  testaceous,  the  antennae  and  trophi  pale  as  usual,  the 
female  a  little  paler  than  the  male;  head  nearly  as  in  the  preceding 
though  relatively  not  quite  so  large;  prothorax  much  shorter, 
two-fifths  to  nearly  one-half  wider  than  long,  similarly  with  basally 
converging  sides  and  base  somewhat  narrower  than  apex,  the  surface 
and  obtuse,  narrowly  rounded  basal  angles  also  similar;  elytra  three- 
fifths  to  two-thirds  longer  than  wide,  much  less  convex  than  in 
collucens  but  similar  in  this  respect  to  erraticus,  the  striae  deeply 
impressed  and  the  intervals  strongly  convex  and  almost  equally 
shining  in  both  sexes,  the  sinus  deepest  externally,  the  outer  angle 
sharp  but  very  obtuse,  scarcely  more  so  in  the  male  than  in  the 
female;  marginal  line  of  foveae  sparse,  smaller  and  confused  medially 
but  not  interrupted;  abdomen  with  the  basal  punctures  very  nu- 
merous, strong  and  conspicuously  setigerous.  Length  (cf  9  )  n.o—

before  the  basal  angles,  which  are  distinctly  more  than  right.  Body 
very  much  larger  in  the  female  than  in  the  male,  the  apical  sinus 
of  the  elytra  broad  as  usual,  rather  feeble  and  broadly  curved  (cf ), 
or  deeper  externally  (9  ),  the  angle  very  broadly  obtuse  and  some- 
what rounded  in  the  former,  nearly  right  and  rather  sharply  marked  as 
a  rule  in  the  latter,  sex;  head  relatively  a  little  larger  than  in  aco- 
manus but  otherwise  nearly  similar;  prothorax  much  more  evidently

narrower  than  the  elytra  in  both  sexes,  fully  a  third  to  two-fifths 
wider  than  long,  nearly  similar  in  outline  and  surface  and  with 
similarly  notably  converging  sides  toward  base,  where  however 
they  become  straight  and  not  feebly  arcuate  as  in  all  the  preceding 
species,  the  angle  obtuse  but  sharp  and  generally  slightly  prominent 
externally;  diffused  latero-basal  punctures  distinct,  the  foveae  large 
and  feeble  as  usual;  elytra  three-fifths  to  two-thirds  longer  than  wide, 
parallel  and  broadly  rounded  at  the  sides,  barely  at  all  less  shining 
in  the  female  than  in  the  male,  the  surface  throughout  nearly  as  in 
acomanus,  the  tarsi  nearly  similar.  Length  (cT  9  )  12.0-16.0  mm.; 
width  4.0-5.8  mm.  New  Mexico  and  Arizona.  Thirteen  examples. 

[Harpalus  impiger  \\  Lee.] retractus  Lee. 

Sides  of  the  prothorax  conspicuously  sinuate  posteriorly,  becoming 
parallel  and  straight  for  a  considerable  distance  before  the  angles, 
which  are  absolutely  right  and  sharply  marked,  not  at  all  prominent 
externally.  Body  (cf)  unusually  narrow  in  form,  moderately 
convex,  shining,  piceous-black,  red-brown  beneath,  the  legs  tes- 
taceous; head  nearly  as  in  the  preceding  and  similarly  with  the 
shallow  concavity  surrounding  the  small  deep  punctiform  frontal 
foveae  obsolete;  prothorax  only  about  a  fourth  wider  than  long,  the 
sides  broadly  rounded  anteriorly,  the  base  fully  as  wide  as  the  apex 
and  distinctly  sinuato-truncate,  finely  but  deeply  margined;  latero- 
basal  punctures  strong  and  close-set;  elytra  not  quite  a  fourth  wider 
than  the  prothorax,  nearly  three-fourths  longer  than  wide,  parallel, 
with  broadly  rounded  sides,  the  apical  sinus  broadly  curved  exter- 
nally, with  the  obtuse  angle  rounded;  striae  deeply  impressed,  the 
intervals  strongly  convex  and  polished;  humeri,  as  usual,  not  in  the 
least  denticulate.  Length  (c?)  13.3  mm.;  width  4.7  mm.  Arizona. 
A  single  specimen rectangulus  n.  sp. 

In  his  original  description  of  retractus  (Proc.  Acad.  Phila.,  1854, 
p.  79),  under  the  name  impiger,  LeConte  states  that  the  elytra 
are  unipunctate.  Among  the  rather  numerous  examples  of  the 
various  species  before  me,  I  am  unable  to  discover  a  single  discal 
setigerous  puncture  and  am  therefore  at  a  loss  to  account  for  the 
statement  quoted.  In  most  of  the  species  there  is  no  great  sexual 
disparity  in  the  size  of  the  body,  but  in  retractus  this  becomes  a  very 
conspicuous  character  of  the  species.  The  mentum  usually  has  a 
small  or  very  short  and  more  or  less  obtuse  tooth,  which  in  retractus 
is  broadly  rounded. 

Group  III   (viridicBneus) . 
Subgenus  Harpalophonus  Gangl. 

Our  single  representative  of  this  group,  which  is  much  more 
developed  in  the  palsearctic  fauna,  is  a  small,  parallel  and  rather 


HARPALIN^E  75 

convex  species,  very  variable  in  color,  in  the  discal  elytral  puncture 
and  also  varying  in  the  number  and  disposition  of  the  epistomal 
setae  in  a  most  unusual  manner.*  The  mentum  has  constantly  a 
moderate  and  broadly  triangular  tooth.  The  species  may  be 
described  as  follows: 

Form  oblong,  parallel,  convex,  shining  throughout  (cf),  the  elytra  alu- 
taceous  (9),  black  above  and  beneath  when  mature,  the  legs 
blackish-piceous  to  paler,  the  antennae  and  trophi  obscure  testaceous; 
upper  surface  varying  from  obscure  viridi-aeneous  to  bright  green 
or  cupreous,  the  anterior  parts  sometimes  green  with  the  elytra 
cupreous;  head  moderate,  the  antennae  extending  behind  the 
thoracic  base;  prothorax  one-half  wider  than  long,  the  sides  parallel, 
broadly  rounded  anteriorly,  less  so  basally,  the  base  transverse, 
strongly  margined,  feebly  bisinuate  and  slightly  wider  than  the 
apex,  the  angles  slightly  obtuse  and  rounded;  apex  sinuate,  with 
broadly  rounded  angles;  surface  steeply  sloping  at  the  sides  to  the 
finely  reflexed  edge,  the  latero-basal  regions  distinctly  punctured, 
the  foveae  large  but  feeble  and  vague,  separated  from  the  sides  by  a 
convex  surface,  the  median  stria  distinct;  elytra  parallel,  about  as 
wide  as  the  prothorax,  two-thirds  longer  than  wide,  obtuse  at  apex, 
the  sinus  nearly  as  in  Group  II,  deep  externally,  where  it  is  limited 
by  an  obtuse  dentiform  projection;  surface  smooth,  diffusedly 
punctate  on  the  flanks  and  toward  tip,  the  striae  moderately  fine 
and  impressed,  the  scutellar  long  but  seldom  joining  the  first,  the 
discal  puncture  very  inconstant;  abdomen  with  fine  suffused  punc- 
tures bearing  short  hairs  and  rather  irregularly  distributed,  equal 
among  themselves  and  largely  wanting  toward  the  sides;  hind  tarsi 
rather  short,  the  first  two  joints  equal,  two  to  four  decreasing,  the 
first  much  shorter  than  the  fifth;  metasternum  laterally  and  its 
episterna  punctate  as  usual.  Length  (cf  9  )  9.0-10.8  mm.;  width 
3.2-4.0  mm.  Rhode  Island  to  Lake  Superior.  [//.  viridis  Say,  as- 
similis  Dej.  and  canonicus,  convictor,  cenescens  and  lustralis  Csy.]. 

viridiaeneus   Beauv. 

The  peculiar  form  of  the  elytral  sinus,  reproducing  that  of  the 
preceding  group  and  observable  nowhere  else  in  the  genus,  is 
exactly  similar  to  that  of  an  example  in  my  collection  labeled 
Harpalophonus  hospes  Sturm,  from  the  European  fauna;  as  there 
are  also  many  other  points  of  resemblance,  I  do  not  hesitate  to 
place  this  species  in  that  subgenus. 

*  In  days  of  early  inexperience  and  with  the  idea  that  duplication  of  the  epistomal 
punctures  might  be  important  here  as  well  as  in  the  Anisodactylini,  as  stated  by  Horn 
(Proc.  Am.  Phil.  Soc.,  1880,  p.  162),  I  described  four  species  from  as  many  individuals 
of  this  species  (Cont.  Descr.  Syst.  Col.  N.  A.,  I,  p.  n),  a  mistake  which  proved  to  be 
most  unfortunate  in  subsequent  years  from  many  points  of  view.

Group  IV  (amputatus}. 
Subgenus  Harpalomerus  nov. 

Another  very  isolated  type  seems  to  require  subgeneric  desig- 
nation as  above.  The  body  is  oblong  and  subparallel  and  the  upper 
surface  is  generally  pervaded  by  metallic  blue  or  green  gloss  as  in 
the  preceding  group,  though  always  of  a  darker  shade  when  present; 
but  it  is  chiefly  distinguished  by  the  form  of  the  elytral  apices, 
which  are  transversely  truncate,  with  prominent  sutural  angle  in 
the  female  though  obliquely  subsinuate  in  the  male.  The  single 
discal  puncture  is  apparently  constant  and  I  have  noted  only  one 
example  where  there  is  a  gemination  of  the  epistomal  punctures  and 
this  only  on  one  side.  There  are  three  forms  in  my  collection, 
which  are  probably  specific  in  nature  as  follows : 

Upper  surface  with  dark  blue  to  greenish  metallic  lustre 2 

Upper  surface  without  trace  of  metallic  lustre 3 

2 — Body  parallel,  moderately  stout  and  convex,  polished,  black  when 
mature,  a  little  less  deep  beneath,  the  legs  obscure  rufous,  the  femora 
generally  black,  the  upper  surface  with  deep  violet-blue  to  green 
metallic  lustre  on  the  elytra,  barely  observable  however  on  the  head 
and  prothorax,  the  elytra  alutaceous  in  the  female;  head  moderate, 
three-fifths  as  wide  as  the  prothorax,  smooth,  with  prominent  eyes, 
the  antennae  extending  slightly  beyond  the  thoracic  base;  prothorax 
one-half  (cf)  to  three-fifths  (9)  wider  than  long,  parallel,  almost 
evenly  rounded  at  the  sides,  the  basal  angles  broadly  rounded  and 
obliterated,  the  base  margined,  -transverse,  about  as  wide  as  the 
sinuate  apex,  the  anterior  angles  very  broadly  rounded;  surface 
very  steeply,  rather  abruptly  declivous  at  the  sides  to  the  narrow 
reflexed  edge,  which  broadens  and  shallows  slightly  behind,  the 
foveae  large,  rather  deeply  impressed  and  strongly  punctate,  the 
punctures  also  often  but  not  always  scattered  thence  over  the 
convex  surface  separating  the  foveae  from  the  sides;  median  stria 
very  fine;  elytra  about  one-half  longer  than  wide,  very  slightly 
wider  than  the  prothorax,  parallel,  the  striae  rather  strong  and  deep, 
the  scutellar  long,  not  or  but  very  seldom  joining  the  first;  apical 
truncature  ( 9  )  transverse,  straight,  gradually  becoming  posteriorly 
prominent  toward  the  dentiform  sutural  angles,  or  (cf)  oblique 
and  obsoletely  sinuate  and  without  dentiform  sutural  angles; 
abdomen  with  sparse  punctulation,  somewhat  as  in  the  preceding 
group  but  less  extended;  hind  tarsi  with  the  first  three  joints  rather 
slowly  decreasing,  the  fourth  more  abruptly  shorter,  the  first  much 
shorter  than  the  fifth.  Length  (cf  9  )  9.5-11.0  mm.;  width  3.3-4.1 
mm.  New  Mexico,  Arizona,  Colorado  and  Utah.  Forty  examples. 

amputatus  Say 

Body  parallel,  very  much  broader  than  in  the  preceding,  the  metallic 
coloration  confined  to  the  elytra,  deep  violaceous-black  (cf ),  almost 


HARPALIN/E  77 

wanting  or  more  greenish  (  9  ),  the  general  characters  as  in  amputatus, 
the  prothorax  much  more  transverse  though  with  similarly  very 
broadly  rounded  basal  angles,  fully  two-thirds  wider  than  long,  the 
surface  nearly  similar;  elytra  shorter,  much  less  than  one-half  (cf), 
to  two-fifths  (9),  longer  than  wide,  with  broadly  arcuate  sides, 
barely  wider  than  the  prothorax,  the  apical  truncature  ( 9  )  wider, 
straighter  and  only  becoming  denticularly  prominent  at  the  suture 
itself;  tarsi  somewhat  longer.  Length  (cf  9  )  n.o  mm.;  width  4.2- 

4.4   mm.     New  Mexico.     Three   examples transversus  n.  sp. 

3 — Form  oblong,  moderately  convex,  testaceous  in  color,  the  elytra 
alutaceous  in  the  female  and  without  trace  of  metallic  lustre,  the 
head  as  in  the  others,  the  mandibles  closely  and  finely  strigose; 
antennae  a  little  shorter;  prothorax  nearly  two-thirds  wider  than  long, 
as  in  amputatus,  except  that  the  basal  angles  though  obtuse  are 
much  less  broadly  rounded  and  not  obliterated;  elytra  short,  oblong, 
with  broadly  rounded  sides,  two-fifths  longer  than  wide  and  very 
distinctly  wider  than  the  prothorax,  the  apical  truncature  not 
transverse  as  in  the  two  preceding,  but  distinctly  oblique  from  the 
broadly  rounded  external  angles  to  the  prominent  and  apically 
everted  sutural  angles  and  very  feebly  sinuate;  under  surface  and 
legs  still  paler  than  the  upper  surface;  hind  tarsi  more  slender  than 
in  either  of  the  preceding.  Length  (9)  9.0  mm.;  width  3.5  mm. 
Arizona.  A  single  example papagonalis  n.  sp. 

It  is  quite  certain  that  the  type  of  papagonalis  is  immature  to 
some  extent  and  that  the  normal  coloration  is  darker,  but  there  is 
no  contraction  or  distortion  due  to  drying;  in  any  event,  the  form 
of  the  elytral  tips  and  basal  thoracic  angles,  as  well  as  total  absence 
of  the  metallic  coloration,  which  is  always  observable  even  in  the 
palest,  most  immature  and  testaceous  examples  of  amputatus,  will 
readily  identify  the  species;  it  is  also  materially  smaller  in  size  in 
all  probability. 

Group  V  (pennsylvanicus] . 

This  group  includes  a  considerable  number  of  forms,  numbering 
among  them  our  commonest  species,  pennsylvanicus,  erythropus, 
and  compar  being  extremely  abundant  almost  everywhere  east  of 
the  Rocky  Mountains;  it  is  also  a  very  usual  type  of  the  genus 
throughout  Europe  and  Asia.  The  body  is  in  general  rather 
elongate,  the  pronotum  flattened  and  strongly,  generally  densely 
punctate  postero-externally  and  with  the  basal  angles  distinct  as  a 
rule  and  but  slightly  blunt  or  rounded,  though  never  sharply 
marked,  it  being  one  of  the  decisive  marks  of  the  true  Harpalus 
throughout,  that  the  angles  are  never  sharply  rectangular  as  in 


78  MEMOIRS  ON  THE  COLEOPTERA 

Cratacanthus  or  Pharalus  but  always  blunt  and  sometimes  rather 
broadly  rounded ;  it  is  only  in  very  rare  cases,  such  as  pleuriticus 
Kirby,  that  the  basal  angles  become  in  any  way  sharp  at  tip,  and 
even  there  we  find  some  slight  bluntness.  The  pubescent  upper 
surface  of  the  tarsi  constitutes  a  marked  peculiarity  of  this  group. 
Our  species  may  be  defined  as  follows: 

Elytra  without  a  dorsal  setigerous  puncture 2 

Elytra  with  a  distinct  dorsal  puncture  just  outside  the  second  stria,  well 
behind  the  middle 15 

2 — Elytra  of  the  female  evenly  and  rather  closely  punctured  virtually 

throughout,  the  punctures  sparser  and  limited  to  the  lateral  parts 

•    of  the  surface  in  the  male 3 

Elytra  not  punctured  throughout  in  either  sex,  rarely  impunctate  in 
both  sexes  as  in  erythropus 4 

3 — Body  moderate  in  size  and  width  or  rather  narrow,  elongate,  very 
moderately  convex,  black  or  piceous-black  above  and  beneath, 
somewhat  shining  (cf),  the  elytra  opaculate  (9);  legs,  antennae 
and  trophi  bright  testaceous  throughout;  head  two-thirds  as  wide 
as  the  prothorax,  differing  but  little  sexually,  the  eyes  prominent, 
the  foveae  minute,  perforato-punctate,  at  the  bottom  of  large  feeble 
impressions;  antennae  long,  very  slender,  extending  far  beyond  the 
prothorax,  which  is  about  a  third  wider  than  long,  broadly,  evenly 
rounded  at  the  sides  from  apex  to  base,  the  latter  transverse, 
margined  and  distinctly  wider  than  the  apex,  the  angles  obtuse  and 
narrowly  blunt,  the  apex  shallowly  sinuate;  surface  broadly  sub- 
deplanate  and  closely  punctate  latero-basally,  the  margins  rather 
coarsely  reflexed,  the  foveae  large  but  shallow;  median  line  fine  but 
rather  broadly  impressed;  elytra  three-fourths  longer  than  wide, 
about  a  fifth  wider  than  the  prothorax,  parallel,  feebly  arcuate  and 
narrowly  reflexed  at  the  sides,  ogival  at  apex,  the  sinus  shallow,  even 
and  evident;  surface  (c?)  shining,  rather  strongly  striate,  thescutellar 
stria  very  long  but  free,  the  intervals  feebly  convex,  the  outer  four 
with  sparse  feeble  diffused  punctures,  the  next  three  with  very  few 
widely  scattered  punctures  of  the  same  kind,  or  (  9  )  with  even  distinct 
punctures  throughout;  hind  tarsi  long,  the  basal  joint  nearly  one- 
half  longer  than  the  second  and  longer  than  the  fifth,  the  tarsi  ( 9  ) 
shorter  and  still  more  slender;  in  both  sexes  they  are  finely  pubescent 
above  and  coarsely  setose  beneath;  claws  moderate,  arcuate,  feebly 
subdentate  internally  at  base.  Length  (cT  9  )  12.0-14.3  mm.; 
width  4.2-5.3  mm.  Indiana  and  Missouri  (St.  Louis).  Six  examples. 

vagans  Lee. 

Body  much  larger  and  stouter,  rather  more  convex,  similar  in  lustre  and 
coloration,  the  head  larger,  three-fourths  as  wide  as  the  prothorax, 
the  perforate  foveae  less  minute;  mandibles  similarly  smooth  and 
convex  above;  antennae  rather  long  though  not  extending  behind  the 
thoracic  base;  prothorax  more  transverse,  nearly  one-half  wider 
than  long,  otherwise  nearly  similar,  except  that  the  latero-basal

sculpture  is  much  coarser,  denser  and  more  rugose  throughout; 
elytra  relatively  much  shorter,  three-fifths  longer  than  wide,  parallel, 
broadly  rounded  at  the  sides,  very  obtuse  at  tip,  the  sinus  very  feeble 
though  evident;  surface  (cf)  very  shining,  the  intervals  strongly 
convex  suturad,  the  two  outer  rather  closely,  the  next  one  more 
sparsely,  suffusedly  punctate,  the  next  two  with  a  few  sparse  punc- 
tures, more  evident  basally,  or  ( 9  )  strongly,  closely,  very  uniformly 
punctured  throughout,  more  strongly  so  than  in  vagans;  tarsi  nearly 
similar  in  structure.  Length  (cf  9  )  16.5-17.0  mm.;  width  5.9-6.2 
mm.  Iowa  (Keokuk)  and  Missouri  (St  Louis).  Three  examples. 

actiosus  n.  sp. 

Body  larger  and  more  convex  than  in  vagans  and  deeper  black  in  color, 
much  more  slender  and  smaller  than  in  actiosus,  deep  black,  the  legs, 
trophi  and  antennae  pale  testaceous;  head  rather  large,  fully  two- 
thirds  as  wide  as  the  prothorax;  mandibles  black  throughout; 
prothorax  a  third  wider  than  long,  not  so  transverse  as  in  vagans 
but  otherwise  almost  similar,  slightly  more  convex,  with  the  median 
stria  finer;  elytra  (9)  more  elongate,  fully  two-thirds  longer  than 
wide,  otherwise  nearly  similar,  except  that  the  intervals  are  less 
flat  and  differing  from  the  female  of  both  the  preceding  species, 
where  the  small  close-set  punctures  attain  the  suture  without  change 
of  character  or  density,  in  having  the  close-set  punctures  end 
abruptly  at  the  first  stria,  the  sutural  interval  with  scarcely  any 
punctures,  a  few  being  visible  basally.  Male  slightly  stouter  than 
in  vagans,  almost  similarly  punctured.  Length  (cf  9  )  12.0-16.0 
mm.;  width  4.4-5.5  mm.  Pennsylvania  and  Long  Island.  Three 
examples haldemani  n.  sp. 

4 — Punctuation  toward  the  basal  thoracic  angles  fine,  sometimes  with 
larger  punctures  intermingled,  the  surface  there  not  so  abruptly  or 
so  strongly  flattened 5 

Punctuation  toward  the  angles  decidedly  coarse,  the  surface  abruptly 
and  more  exactly  flat 1 1 

5 — Elytra  not  punctured  on  the  flanks  in  either  sex;  body  smaller  in  size; 
head  moderate 6 

Elytra  with  suffused  punctulation  near  the  sides  in  both  sexes,  but  so 
minute  as  only  to  be  seen  when  carefully  observed;  body  large;

Longicollis  Lee.,  is  stated  by  Horn  to  be  the  same  as  longior 
Kirby,  but  as  this  is  doubtful  to  some  extent,  I  have  not  made  the 
change.  A  singular  characteristic  of  nearly  all  the  species  is  the 
fact  that  the  larger  examples  in  each  sex  are  proportionally  stouter 
than  the  smaller  ones,  and  for  this  and  other  reasons  it  is  a  difficult 
operation  to  properly  segregate  the  species  in  a  miscellaneous 
mixture  of  material,  but  the  species  are  nevertheless  well  denned, 
as  a  rule,  and  the  placing  of  compar  and  erythropus  as  varieties  of 
pennsylvanicus  in  the  Henshaw  list  is  a  gross  error.  The  hairy 
upper  surface  of  the  tarsi  isolates  this  group  from  every  other  in 
our  fauna  but  because  of  its  inconstancy  can  scarcely  be  regarded 
as  a  generic  character;  it  affects  as  well  the  similar  European  and 
Chinese  species  that  are  among  my  exotic  material.  In  the  Aniso- 
dactylini  use  will  be  made  of  similar  features  in  the  differentiation 
of  certain  genera  allied  to  Dicheirus,  as  it  there  appears  to  be 
more  significant  taxonomically.  The  name  alienus  (1879),  replaced 
above  by  egregius,  is  preoccupied  by  Bates  (Proc.  Zool.  Soc.,  1878,

Group  VI.  (mduus). 

This  is  by  far  the  largest  group  of  the  genus  and  the  species  are 
rather  diversified  in  habitus;  the  vast  majority  are  small,  being 
under  10  mm.  in  length,  but  there  are  some  that  are  notably  large 
by  comparison.  There  is  a  parallelism  in  general  outline  and 
structure  between  some  sections  of  this  group  and  the  next,  so 
marked  in  a  few  cases  as  to  suggest  that  the  presence  or  absence  of 
accessory  abdominal  setae  may  be  purely  arbitrary  as  a  group 
character,  but  it  is  utilized  nevertheless  as  a  convenient  means  of 
dividing  the  horde  of  species  of  these  two  groups  into  sections  more 
readily  aiding  identification  in  dichotomous  tables.  The  mentum 
tooth  is  small  and  inconstant,  being  entirely  obsolete  in  some  species 
such  as  fallax.  Patronus  reproduces  almost  the  exact  facies  of  the 
fraternus  group,  but  there  is  no  trace  of  accessory  abdominal  setae; 
the  absence  of  denticulate  sutural  angles  in  the  female  led  me  to 
believe  that  it  might  be  the  rare  funestus  of  LeConte,  but  that

surface  thence  to  the  sides  almost  flat  and  impunctate;  elytra  un- 
usually long,  two-thirds  longer  than  wide,  between  three  and  four

Colorado  (Boulder  Co.) mobilis  n.  sp. 

The  last  section,  with  small  head,  Celia-like  facies  and  obsolescent 
pronotal  foveae — to  which  paululus  does  not  strictly  belong,  being 
placed  there  solely  on  account  of  the  unusually  small  head, — would 
seem  to  be  at  least  subgenerically  different  from  the  more  typical 
Harpalus,  but  there  are  no  obvious  structural  peculiarities  war- 
ranting the  separation,  other  than  those  mentioned;  the  absence 
of  a  mentum  tooth  similarly  characterizes  many  true  Harpalus 
species,  such  as  herbivagus  and  fallax.  The  above  description  of 
megacephalus  is  taken  from  the  original,  as  I  do  not  seem  to  have 
that  species  in  my  collection.  There  are  also  a  number  of  other 
species  unknown  to  me,  that  apparently  belong  to  this  viduus  group 
according  to  LeConte;  these,  accompanied  by  descriptions  drawn 
directly  from  the  originals,  are  as  follows: 

H.  fulvilabris  Mann. — Oblong,  black;  prothorax  short,  wider  than 
long,  subquadrate,  slightly  narrowed  behind,  evidently  canaliculate 
medially,  the  base  obsoletely  foveolate  at  each  side,  finely  and,  about  the 
foveae  densely,  punctulate,  all  the  angles  rounded;  elytra  striate,  shining 


HARPALIN^;  113 

(cf),  opaque  (9),  the  apices  obliquely  truncate,  slightly  sinuate,  the 
third  interval  with  two  impressed  punctures  [whether  on  each  elytron  or 
the  two  combined  not  stated];  trophi  and  mandibles,  palpi  and  labrum, 
limb  of  the  prothorax  and  elytra  narrowly,  the  margins  reflexed,  and  the 
antennae  and  legs  rufous.  Length  8-9  mm.;  width  3.3-4  mm.  Alaska 
(Kodiak  Island). 

Evidently  different  from  any  known  to  me;  the  language  referring 
to  the  elytral  puncture  is  puzzling. 

H.  ventralis  Lee. — Oblong-oval,  parallel,  subdepressed,  nigro-piceous 
above;  head  smooth,  the  frontal  suture  distinct,  the  frontal  impressions 
minute;  mouth,  antennae  and  palpi  rufo-piceous;  prothorax  one-half 
wider  than  the  head,  not  shorter  than  wide  [!],  quadrate,  anteriorly 
slightly  emarginate,  with  the  sides  rounded  anteriorly,  posteriorly  nearly 
straight,  the  base  truncate,  with  the  hind  angles  perfectly  right,  obsoletely 
explanate;  transverse  impressions  almost  obsolete,  the  stria  fine,  the 
basal  foveae  linear,  not  deep;  elytra  feebly  sinuate  at  tip,  striate,  the  striae 
fine,  deeper  posteriorly,  the  intervals  flat;  under  surface  and  legs  wholly 
pale  rufo-piceous.  Length  8.7  mm.;  width  3.7  mm.  Near  Long's  Peak. 

The  statement  in  regard  to  the  form  of  the  prothorax  of  this 
species  prevents  the  assignment  to  it  of  any  known  to  me.  No 
mention  is  made  of  any  peculiarity  relating  to  the  abdomen  or 
hind  body,  as  the  name  would  seem  to  imply. 

H.  opacipennis  Hald.  (Ophonus) — Oval,  glossy,  chestnut-brown 
beneath  and  upon  the  middle  and  posterior  thighs;  antennae,  palpi, 
margin  of  the  labrum,  intermediate  and  posterior  tibiae  and  tarsi  and 
anterior  legs  rufous;  head  with  a  small  round  indentation  upon  each  side 
between  the  antennae;  pronotum  much  wider  than  long,  transversely 
rugulose,  with  the  basal  impressions  rugose,  shallow,  each  with  a  very 
slight  fossula;  dorsal  lines  faint;  elytra  finely  and  simply  striate;  inter- 
stices flat,  with  a  puncture  upon  the  third  one;  tip  slightly  sinuate; 
surface  sericeous.  Length  9  mm.  Southeastern  Pennsylvania. 

I  cannot  refer  any  one  of  the  new  forms  here  described  to  this 
species.  Although  both  plenalis  and  latebricola  have  the  opaculate 
elytra,  the  legs  are  clear  and  uniform  testaceous  throughout. 
Opacipennis  may  come  just  before  plenalis  in  the  table. 

H.  carbonatus  Lee. — Elongate-oblong,  being  somewhat  as  in  cautus 
(advena  Lee.)  but  with  basal  thoracic  angles  less  rounded;  head  obtuse, 
the  eyes  moderately  prominent;  prothorax  wider  than  the  head,  shorter 
than  wide,  slightly  narrowed  posteriorly,  the  sides  broadly  rounded, 
obsoletely  explanate  posteriorly,  the  hind  angles  right,  with  their  tips 
rounded;  basal  foveae  small,  not  at  all  deep  and  sparsely  punctate; 
elytra  (9  )  opaque,  the  apices  not  at  all  sinuate;  striae  impunctate,  the 
intervals  slightly  convex;  antennae  and  palpi  piceo-rufous.  Length 
10  mm.  Saskatchewan.

H4  MEMOIRS  ON  THE  COLEOPTERA 

The  species  named  fugitans  in  the  table  came  to  me  under  the 
above  name,  but  does  not  agree  well  with  LeConte's  short  descrip- 
tion ;  the  form  in  fugitans  is  much  shorter  and  more  depressed  than 
in  cautus,  the  hind  angles  of  the  prothorax  rather  broadly  rounded 
and  the  legs  varicolored — rufous,  with  black  femora.  The  elytral 
sinus,  also,  while  feeble,  is  quite  evident  and  the  size  is  much 
smaller.  It  may  be  placed  next  to  fugitans  for  the  present. 

The  specimen  serving  for  the  description  of  innocuus  Lee.,  in 
the  table,  is  doubtless  immature,  as  the  body  is  said  to  be  black, 
with  the  tibiae  and  tarsi  obscure  ferruginous,  in  the  original  female 
type  of  that  species,  leaving  it  to  be  inferred  that  the  femora  are 
dark;  the  legs  in  the  example  described  above  are  absolutely  clear 
and  pale  flavo-ferruginous  throughout.  However,  as  it  is  from 
the  same  locality  and  the  other  characters  agree,  I  suppose  that  it 
is  properly  identified. 

Gemmeus  is  a  remarkably  aberrant  species  and  might  with  some 
propriety  form  a  group  by  itself;  the  frontal  foveae,  elytral  striation 
and  general  coloration  are  all  notably  distinctive. 

The  name  viduus  was  originally  assigned  as  a  cabinet  name  by 
LeConte  to  a  New  Jersey  species,  here  apparently  described  under 
the  name  recisus,  but,  as  no  description  was  given,  this  original 
viduus  must  be  considered  a  purely  manuscript  name;  that  it  was 
evidently  so  regarded  by  LeConte  himself  is  proved  by  the  fact 
that  he  subsequently  (Proc.  Acad.  Phila.,  1865,  p.  103)  gave  the 
name  to  another  quite  different  species  from  Illinois.  The  language 
used  in  coarse  print  remarks  under  the  description  of  fallax  (Col. 
Kansas,  p.  3)  is  this:  "A  very  similar  nondescript  species  from 
New  Jersey  was  kindly  given  me  by  Mr.  Guex;  it  differs  chiefly 
by  the  thorax  being  broader,  with  the  sides  less  rounded  and  less 
narrowed  anteriorly.  I  have  named  it  H.  viduus."  It  is  easy  to 
see  that  this  was  not  intended  in  any  way  as  a  description,  and  I 
therefore  have  to  differ  with  Chaudoir  (Rev.  Mag.  Zool.,  1868, 
p.  20)  in  his  contention  that  the  second  viduus  should  have  its 
name  changed  because  of  preoccupation.  Furthermore,  the  few 
characters  given  to  distinguish  the  original  viduus  from  fallax, 
seem  to  be  inaccurate;  at  any  rate  they  do  not  apply  in  any  way 
to  recisus. 


HARPALIN/E  1 15 

Group  VII   (fraternus). 

The  general  habitus  of  the  body  is  even  more  varied  in  this 
group  than  in  the  preceding,  but  all  the  species  have  on  the  ab- 
domen, outside  of  the  two  regular  longitudinal  series  of  setse,  a 
number  of  additional  setae  arising  from  more  or  less  asperate 
punctures,  scattered  very  irregularly  and  sparsely  over  the  surface 
as  a  rule,  generally  shorter  and  less  erect  than  the  regular  setae 
of  the  series  and  termed  accessory  setae  by  LeConte.  Sometimes 
these  setae  are  reduced  to  a  very  small  number,  perhaps  not  more 
than  two  or  three  in  an  isolated  cluster  that  may  readily  be  over- 
looked, as  in  the  case  of  lewisi,  which  was  placed  in  company  with 
laticeps  of  the  preceding  group  by  LeConte  but  which  really  belongs 
here.  The  mentum  tooth  varies  greatly  but  is  much  less  often 
obsolete  than  in  the  viduus  group.  There  are  no  megacephalous 
forms,  such  as  laticeps,  but  in  renoicus  and  sejunctus  the  head  be- 
comes as  small  as  in  n'tidulus  and  allies  of  the  preceding  group, 
accompanied  by  an  almost  similar  general  habitus  of  the  body. 
The  desertus  section  seems  however  to  be  peculiar  to  this  fraternus 
group  in  habitus,  and  the  posteriorly  oblique  sides  of  the  thoracic 
base  and  pale  integuments  impart  a  distinctive  appearance.  The 
species  are  not  so  numerous  as  in  the  viduus  group,  those  known  to 
me  being  definable  as  follows : 

Body  larger  in  size,  always  over  10  mm.  in  length  and  of  very  broad, 
frequently  subdepressed  form;  mentum  tooth  generally  of  feeble 
development  and  more  or  less  broadly  rounded 2 

Body  smaller,  about  10  mm.  in  length,  narrower  and  more  parallel; 
mentum  tooth  completely  wanting,  the  bottom  of  the  emargination 
transverse  and  even ' 6 

Body  still  smaller,  generally  much  under  10  mm.  in  length,  of  narrow, 
suboval  or  oblong-oval  form,  the  mentum  tooth  rather  well  developed 
as  a  rule  and  often  very  acute,  wanting  in  oppositiis 7

In  regard  to  albionicus,  Mannerheim  states  that  the  base  of  the 
prothorax  is  punctulate;  this  language  could  not  apply  to  any  of 
the  rather  numerous  examples  at  hand,  which,  answering  all  the 
other  described  characters,  seem  to  be  correctly  identified;  it  was 
surmised  by  LeConte  that  the  type  of  albionicus  might  be  merely 
an  immature  example  of  cautus,  but  this,  according  to  the  terms  of 
the  description,  is  not  at  all  probable.  The  description  of  funestus, 
given  above,  is  from  the  original. 

A  few  species  of  the  fraternus  group  are  still  unknown  to  me; 
these  are  described  as  follows  from  the  original  diagnoses. 

H.  clandestinus  Lee. — Elongate,  oblong-oval,  piceous-brown;  an- 
tennse,  palpi  and  legs  rufo-testaceous;  prothorax  wider  than  long,  the 
sides  rounded  in  front,  then  nearly  straight,  but  very  feebly  sinuate  to 
the  hind  angles,  which  are  rectangular,  not  at  all  rounded;  base  emargin- 
ate,  the  side  margin  more  reflexed  than  usual,  explanate  and  sparsely 
punctulate  toward  the  base,  the  basal  impressions  narrow,  slightly 
punctured;  elytra  not  wider  than  the  prothorax,  the  striae  deep,  impunc- 
tured,  the  intervals  slightly  convex;  dorsal  puncture  upon  the  third 
stria;  outline  oblique  toward  tip  but  not  sinuate;  abdomen  with  accessory 
setae,  the  first  segment  punctured  behind  the  coxae.  Length  8.5  mm. 
Colorado  (Garland — 8000  feet).  A  single  male. 

It  is  said  to  resemble  furtivus  but  to  differ  in  having  the  hind 
angles  of  the  prothorax  rectangular  and  not  rounded.  As  indicated 
by  the  emarginate  base  of  the  prothorax,  it  should  be  placed  in  the 
furtivus — nugax  section  as  arranged  above,  but  it  differs  from  any 
one  of  the  species  known  to  me  by  the  unrounded  thoracic  angles. 

H.  stupidus  Lee. — Oblong,  suboval,  convex,  black;  prothorax  more 
than  one-half  wider  than  long,  the  sides  finely  margined,  rounded  anter- 
iorly, nearly  straight  posteriorly  and  almost  parallel,  the  hind  angles 
right,  slightly  rounded,  the  basal  foveae  not  at  all  deep,  the  entire  basal 
region  punctulate;  elytra  with  impunctate  striae,  opaque  in  the  female, 
the  intervals  slightly  convex,  the  apices  sinuate;  antennae  and  legs 
obscure  ferruginous.  Length  11.5  mm.  Nebraska  (near  Fort  Bridger).

It  is  said  to  have  somewhat  the  appearance  of  funestus,  which 
however  has  black  legs  and  is  otherwise  quite  different,  it  may  be 
placed  just  after  junestus  in  the  table. 

H.  obesulus  Lee. — Oblong-oval,  slightly  convex,  black,  shining; 
prothorax  almost  twice  as  wide  as  long,  narrowed  at  apex,  the  margin 
not  depressed;  hind  angles  right,  the  base  obsoletely  bi-impressed 
["  utrinque  obsolete  biimpresso  "  in  the  original],  slightly  rugoso-punctu- 
late;  elytra  a  little  wider  than  the  prothorax,  the  apices  obliquely  sinu- 
ate, the  striae  deeper  posteriorly;  intervals  slightly  convex,  the  third 
unipunctate;  antennae  testaceous  at  base.  Length  8.7  mm.  Oregon. 
A  single  female  example. 

This  species  is  now  considered  a  synonym  of  basilaris  Kirby, 
but  how  justly  I  have  no  way  of  knowing  in  the  absence  of  authen- 
tically identified  examples  of  Kirby's  species,  which  comes  from 
the  far  north,  Lat.  54°,  and  has  the  elytra  chestnut-black  and  the 
trochanters  dark  yellow — characters  said  by  LeConte  to  be  at 
variance  with  obesulus.  I  am  thoroughly  disposed  to  doubt  the 
present  synonymy  and  also  doubt  the  synonymy  of  desertus  Lee., 
with  ochropus  Kirby,  as  at  present  maintained;  desertus  is  from  a 
far  more  southern  habitat. 

H.  varicornis  Lee. — Oblong-oval,  subdepressed,  black,  shining; 
head  smooth,  the  foveae  punctiform,  the  frontal  suture  fine,  scarcely 
distinct;  palpi  not  truncate  but  subacute  at  apex;  antennae  black,  the 
first  joint  ferruginous;  prothorax  quadrate,  rather  short,  twice  as  wide  as 
the  head,  fully  one-half  wider  than  long,  slightly  narrowed  anteriorly, 
the  sides  moderately  rounded,  the  base  rectilinearly  truncate,  the  hind 
angles  right,  not  rounded,  feebly  explanate;  transverse  impressions  almost 
obsolete,  the  stria  extremely  fine,  abbreviated  anteriorly,  the  foveae  short 
and  broad,  almost  contiguous  medially,  sharply  separated  from  the 
explanate  angles,  not  deep,  very  finely  and  sparsely  punctate;  elytra 
slightly  sinuate  near  the  apices,  finely  striate,  the  intervals  feebly  convex, 
the  third  posteriorly  unipunctate,  the  scutellar  stria  long;  legs  black. 
Length  8.8  mm.;  width  3.8  mm.  Lake  Superior. 

Allied  possibly  to  sejunctus  and  renoicus  of  the  above  table,  in 
both  of  which  species,  however,  the  first  two  antennal  joints  are 
pale;  it  seems  to  differ  conspicuously  from  either  of  them  in  the 
transversely  and  internally  extended  thoracic  foveae. 

Group  VIII   (spadiceus] . 

There  is  but  little  to  be  said  concerning  this  small  group  of 
two  species,  except  that  in  general  habitus  it  departs  from  any  of 


HARPALIN^E  129 

the  others,  because  of  the  sides  of  the  prothorax  being  straight  or 
sinuate  and  rather  notably  convergent  posteriorly  in  about  basal 
half,  so  that  the  base  is  not  wider  than  the  apex,  as  is  invariably 
the  case  throughout  the  viduus  group,  to  which  it  is  allied  by  the 
pronotal  features,  glabrous  upper  surface  of  all  the  tarsi  and  absence 
of  accessory  abdominal  seta?.  In  spadiceus  the  mentum  has  a  small 
but  distinct  tooth  and  the  ligula  is  narrow,  subparallel  and  not 
dilated  at  apex.  The  species  are  as  follows: 

Form  rather  narrowly  elongate-suboval,  moderately  convex,  shining  in 
both  sexes,  the  elytra  not  at  all  alutaceous  in  the  female;  color  black 
above,  the  under  surface  rufo-piceous,  the  legs  dark  rufous,  the 
slender  antennae  and  the  palpi  testaceous;  head  nearly  three-fourths 
as  wide  as  the  prothorax,  with  very  moderate  and  rather  prominent 
eyes  and  small  perforato-punctiform  fovese;  antennae  extending  well 
behind  the  thoracic  base;  prothorax  relatively  moderate  in  size, 
longer  than  usual,  not  quite  a  third  wider  than  long,  the  sides  rounded 
anteriorly,  converging  and  straight  posteriorly,  the  angles  obtuse, 
with  their  tips  narrowly  rounded;  apex  feebly  sinuate,  with  rather 
narrowly  rounded  angles  and  fully  equal  in  width  to  the  base,  which 
is  transverse  and  finely,  strongly  margined;  surface  steeply  declivous 
at  the  sides  to  the  rather  fine  reflexed  edge,  which  is  virtually  even 
throughout  the  length,  the  foveae  sublinear  but  extremely  feeble  and 
broadly  subimpressed,  finely  and  sparsely  punctured,  the  minute 
punctules  scattered  also  over  the  feebly  convex  surface  thence  to 
the  sides,  the  stria  very  fine  but  subentire;  elytra  about  one-half 
longer  than  wide  and  a  fifth  wider  than  the  prothorax,  obtusely 
ogival  at  apex,  with  parallel,  distinctly  arcuate  sides,  the  sinus  feeble 
though  distinct,  the  sutural  angles  obtuse;  striae  fine  but  deeply 
impressed,  the  scutellar  moderate,  the  intervals  distinctly  convex, 
the  puncture  large  and  deep,  near  apical  third;  hind  tarsi  not  very 
slender,  the  first  three  joints  decreasing  rather  rapidly,  the  first  as 
long  as  the  fifth.  Length  (9)  9-5  mm.;  width  3.6  mm.  A  single 
example  unlabeled  in  the  Levette  collection,  probably  from  Indiana. 

spadiceus  Dej. 

Form  and  size  as  in  spadiceus,  with  similar  prothorax,  except  that  the 
sides  before  the  hind  angles  are  sinuate,  the  angles  rather  rectangular 
and  not  rounded,  the  basal  impressions  of  the  prothorax  deeper  and 
more  elongate;  femora  and  tibiae  blackish,  the  tarsi,  antennae  and 
palpi  rufo-testaceoin.  Otherwise  as  in  spadiceus.  Length  9-9.5 
mm.  North  Carolina  (Black  Mts.) carolinae  Schf. 

Carolina  seems  to  be  distinct  from  spadiceus,  though  we  have 

• 

only  the  very  brief  resume  of  differences  given  above  to  rely  upon ; 
it  is  probably  very  local  in  habitat;  spadiceus  is  rather  widely  dif- 
fused in  the  Atlantic  regions  but  is  not  at  all  common. 

There  are  several  species  described   as  Harpahis,  which   I   am

unable  to  place  anywhere  in  the  series ;  these  are  as  follows  from  the 
original  descriptions: 

H.  comis  Hald. — Shining  black  above  and  upon  the  under  surface 
of  the  head  and  prothorax,  chestnut  brown  beneath;  antennae,  palpi  and 
legs  yellow  testaceous;  head  with  a  small  round  indentation  at  the  inner 
base  of  the  antennae;  pronotum  widest  before  the  middle,  contracted 
behind,  with  the  angles  slightly  obtuse;  basal  impressions  shallow,  some- 
what rugulose;  dorsal  impressions  distinct;  lateral  margin  testaceous; 
elytra  simply  striate,  slightly  sinuate,  the  margin  rufo-piceous  toward 
tip;  interstices  rather  flat,  the  third  with  a  faint  puncture.  Length  8 
mm.;  width  3  mm.  Pennsylvania. 

At  first  LeConte  (Cat.  Col.,  Sm.  Inst.)  thought  that  this  might 
be  the  same  as  spadiceus  Dej.,  but  he  afterwards  concluded  that 
Ophonus  mutabilis  Hald.,  was  the  same  as  the  latter,  leaving  comis 
unidentified.  I  do  not  know  of  any  late  reference  to  the  species. 

H.  curtatus  Mann. — Rather  short  in  form,  parallel,  black  and  shining, 
the  palpi  short;  antennae  and  legs  rufo-ferruginous;  prothorax  very  short 
and  transverse,  twice  as  wide  as  long,  smooth,  the  sides  evenly  and 
moderately  rounded;  all  the  angles  rounded,  the  base  foveolate  at  each 
side,  the  foveae  impunctate;  elytra  striate,  the  third  interval  impunctate. 
Length  7.5  mm.;  width  2.3  mm.  Alaska  (Kenai  Peninsula — \Yoskre- 
sensk  Bay). 

The  antennae  are  said  to  be  only  half  as  long  as  the  head  and 
prothorax  combined.  It  is  evidently  a  peculiar  species,  of  unusually 
small  size  and  may  not  be  truly  a  Harpalus. 

H.  depressicollis  Mots. — Elongate,  subparallel,  somewhat  depressed, 
black,  the  two  basal  joints  of  the  antennae,  the  palpi  and  tarsi  testaceous, 
the  labrum  and  epistoma  margined  with  testaceous,  the  front  with  a 
rufous  spot;  head  rather  short,  with  a  transverse  impression  between  the 
antennae  and  two  minute  diverging  grooves,  which  limit  at  each  side  a 
triangular  cavity,  which  is  somewhat  rugose;  prothorax  slightly  broader 
than  the  head,  depressed,  quadrate,  rather  broadly  margined  at  the 
sides  and  feebly  narrowed  posteriorly;  there  is  at  each  side  of  the  base 
a  shallow  impression,  which  is  covered,  like  the  rest  of  the  basal  region, 
with  a  fine  close  punctuation,  which  diminishes  gradually  toward  the 
middle;  elytra  broader  than  the  prothorax  and  more  than  twice  as  long, 
opaque,  the  second  stria  unipunctate,  the  under  surface  and  epipleura 
dullish  black.  Length  (9)  9.0  mm.;  width  3.3  mm.  California. 

This  species  evidently  belongs  to  the  genus  Anisodactylus ,  for 
the  red  spot  on  the  head  is  frequently  observable  there  but  never  in 
Harpalus,  and  the  pronotal  sculpture  also  agrees  better  with  that 
genus.  I  however  fail  to  recognize  it  among  my  material;  it  is 
more  slender  in  form  than  any  true  Anisodactylus  known  to  me. 


HARPALIN/E  131 

H.  oodioides  Chd. — About  the  size  of  cautus  Dej.,  which  it  much 
resembles  and  it  is  similar  in  coloration;  antennae,  palpi  and  tarsi  dark 
ferruginous,  the  thighs  browner;  head  slightly  smaller,  the  prothorax 
less  convex,  more  deeply  sinuate  at  apex,  a  little  more  narrowed  anteriorly, 
the  posterior  part  of  the  sides  somewhat  less  rounded,  very  feebly  de- 
pressed above;  base  very  slightly  rugose,  the  basal  foveae  narrower  and 
longer;  elytra  less  convex  anteriorly  but  sloping  more  abruptly  toward 
tip,  less  oval,  parallel,  the  humeri  more  nearly  right-angled  and  strongly 
denticulate;  intervals  flatter,  very  finely  micro-reticulate  in  the  male, 
the  female  unknown.  Length  9  mm.  "  Terre  de  Rupert." 

No  remarks  are  appended  to  give  any  further  clue  to  the  true 
position  of  this  species,  which  still  remains  unknown;  it  probably 
belongs  among  the  small-headed  species  at  the  end  of  either  the 
viduus  or  fraternus  group. 

Pteropalus  n.  gen. 

A  few  species  such  as  Harpalus  mdpeculus  Say  and  dichrons  Dej. 
and  Feronia  autumnalis  Say,  have  ever  been  a  source  of  taxonomic 
discomfiture,  being  shifted  from  one  genus  to  another  until  they 
have  finally  brought  up  in  Harpalus,  in  spite  of  recognized  incon- 
gruity. LeConte  assigned  them  to  Bradycelhis  and  in  truth 
autumnalis  does  form  a  genus  near  Bradycelhis,  but  vulpeculus  and 
dichrous  must  form  a  genus  perhaps  having  really  greater  affinity 
with  the  Selenophorids  than  with  Harpalus,  for  which  the  above 
name  is  suggested.  The  prismatic  opalescence  of  the  elytra  is  a 
peculiarity  of  importance,  well  developed  also  in  many  Selenophorid 
groups  but  unknown  in  Harpalus,  and  the  apically  expanded  ligula 
and  externally  prolonged  paraglossae  also  show  that  these  two 
aberrant  species  cannot  remain  in  that  genus.  The  slender  hind 
tarsi,  with  a  very  long  basal  joint — a  peculiarly  constant  character 
in  the  Selenophorini — also  betray  a  wide  departure  from  most  of 
the  genus  Harpalus,  though  there  are  some  species  of  the  pennsyl- 
vanicus  group  approaching  it  very  closely  in  this  respect,  except 
that  the  upper  surface  is  there  more  or  less  pubescent,  as  it  is  in 
the  Selenophorini.  The  mentum  is  more  strongly  and  constantly 
toothed  than  in  Harpalus  and  the  general  habitus  of  the  body  quite 
different.  We  apparently  have  the  four  following  species: 

Sides  of  the  prothorax  rather  strongly  converging  and  broadly  sinuate 
posteriorly,  the  basal  angles  right  and  very  sharply  marked,  not 
even  blunt  at  tip.  Body  oblong-suboval  and  very  moderately

convex,  polished  in  both  sexes,  dark  testaceous,  the  elytra  black, 
with  the  opalescence  feebler  than  in  dichrous,  the  under  surface, 
legs  and  cephalic  appendages  testaceous;  head  fully  three-fifths 
as  wide  as  the  prothorax,  the  eyes  well  developed  and  convex,  the 
foveae  larger  than  usual,  deeply  impressed  and  sublinear  though 
short;  antennae  rather  long,  very  slender;  prothorax  more  than  one- 
half  wider  than  long,  the  sides  rounded  anteriorly,  the  apex  very 
feebly  sinuate  and  as  wide  as  the  base,  which  is  transverse  and 
minutely  beaded;  surface  only  feebly  convex,  rather  broadly  reflexed 
at  the  sides,  the  gutter  equal  as  far  as  basal  third,  where  it  disappears 
on  the  broadly  flattened  and  strongly  punctured  latero-basal  region, 
the  foveae  moderately  impressed  and  punctured,  the  area  of  punctures 
extending  to  the  middle  more  basally;  stria  strong,  almost  entire; 
marginal  puncture  before  the  middle  small  and  very  inconspicuous; 
elytra  one-half  longer  than  wide,  a  third  wider  than  the  prothorax, 
with  parallel  and  rather  strongly  arcuate  sides  and  ogival  apex,  the 
sinus  very  feeble  and  almost  obsolete;  striae  fine  but  rather  deeply 
impressed,  the  scutellar  moderately  long,  free,  the  puncture  small 
and  at  apical  third;  abdomen  not  evidently  punctured  basally; 
hind  tarsi  very  slender,  the  basal  joint  but  slightly  longer  than  the 
next  two  combined.  Length  (c?1  9)  9.0-10.0  mm.;  width  3-35-3-7 
mm.  Indiana  and  Missouri.  [Harpahts  vulpeculus  Say]. 

vulpeculus  Say 

Sides  of  the  prothorax  arcuate  throughout,  less  so  but  only  feebly  con- 
verging basally,  the  hind  angles  obtuse  and  more  or  less  broadly 
rounded;  prothorax  larger  than  in  the  preceding 2 

2 — Body  oblong-oval  or  subparallel,  moderately  convex,  strongly  shining, 
dark  testaceous  throughout  as  in  vulpeculus,  the  elytra  black,  with 
stronger  opalescence  than  in  that  species;  head  not  quite  so  short, 
the  eyes  rather  smaller,  the  foveae  very  much  smaller,  punctiform 
but  lying  in  feeble  impressions;  antennae  rather  long,  very  slender; 
prothorax  not  more  than  two-fifths  wider  than  long,  the  broadly 
rounded  sides  almost  even  throughout,  the  apex  feebly  sinuate,  with 
rather  narrowly  rounded  angles  and  differing  greatly  from  vulpeculus 
in  being  barely  more  than  three-fourths  as  wide  as  the  base,  which  is 
similarly  transverse  and  finely  beaded;  surface  nearly  as  in  the 
preceding,  except  that  the  rather  coarse  marginal  gutter  bends 
inward,  broadens,  becomes  feeble  and  disappears  posteriorly;  an- 
terior transverse  impression  similarly  rather  distinct;  elytra  nearly 
three-fifths  longer  than  wide,  about  a  fifth  wider  than  the  prothorax, 
the  parallel  sides  more  feebly  arcuate,  the  apex  rather  acutely  ogival, 
with  a  feeble  though  evident  sinus;  striae  not  very  fine  and  deeply 
impressed,  the  scutellar  very  long,  parallel  and  free,  the  intervals 
strongly  convex,  highly  polished,  very  strongly  opalescent  and  per- 
fectly similar  in  the  sexes,  the  puncture  small  but  deep  and  much  less 
posterior,  being  at  about  three-fifths;  hind  tarsi  very  slender,  the 
basal  joint  a  little  longer  than  the  next  two  combined.  Length  (cf  9  )

surface  black,  the  head  and  sides  of  the  prothorax  slightly  rufescent, 
the  under  surface  piceous,  the  legs  and  cephalic  appendages  pale 
testaceous;  head  as  in  dichrous  but  with  still  longer,  very  slender 
and  filiform  antennae  and  only  a  little  more  than  half  as  wide  as 
the  prothorax,  which  is  much  larger,  fully  as  wide  as  the  elytra,  a 
little  more  than  two-fifths  wider  than  long,  more  inflated  anteriorly 
and  slightly  more  narrowed  basally,  the  sides  rounded,  becoming 
feebly  so  basally;  apex  sinuate  as  in  the  preceding  but  with  more 
broadly  rounded  angles  and  much  less  obviously  narrower  than  the 
base,  which  is  similar  and  with  slightly  obtuse  and  moderately 
rounded  angles;  surface  nearly  similar  and  with  well  marked,  nearly 
entire  stria  and  rather  distinct  anterior  transverse  impression,  but 
with  the  sides  still  more  coarsely  reflexed,  feebly  punctulate,  the 
deep  gutter  becoming  obsolete  near  basal  third  on  the  rather  flat- 
tened latero-basal  surface,  which  is  sparsely  but  somewhat  strongly 
punctured  from  the  sides  almost  to  the  middle  and  with  two  impres- 
sions, the  regular  foveae  deeper,  more  linear  and  more  distinct  than 
in  dichrous,  and,  between  each  and  the  sides,  another  feeble  discal 
impression;  the  punctures  are  much  sparser  and  less  conspicuous 
toward  the  sides  than  in  the  preceding;  elytra  nearly  as  in  dichrous 
throughout,  except  that  they  are  slightly  more  elongate  and  with 
the  puncture  at  apical  third;  abdomen  similarly  smooth  and  almost 
punctureless,  the  basal  joint  of  the  hind  tarsi  not  quite  so  long, 
being  barely  as  long  as  the  next  two  combined;  mentum  tooth 
rather  narrow  and  strong  but  obtuse  at  tip.  Length  (9  )  n.o  mm.; 

width  4.1  mm.      Missouri  (St.  Louis) fluvialis  n.  sp. 

Body  black,  elytra  iridescent;  legs  piceous,  the  antennae  and  palpi  pale; 
head  narrower  than  the  prothorax,  impunctate,  shining;  piothorax 
about  twice  as  wide  as  long,  the  sides  evenly  arcuate,  the  hind  angles 
obtuse,  rounded;  basal  impression  rather  deep  ajid  linear;  surface 
shining,  without  punctuation,  except  a  very  few  punctures  between 
the  basal  impressions;  elytra  shining  in  both  sexes  and  iridescent, 
the  striae  deeply  impressed,  not  punctate,  the  fovea  distinct  and  on 
the  second  stria;  intervals  slightly  convex;  body  beneath  smooth, 
shining,  the  abdomen  without  accessory  setae,  not  punctulate  basally; 
mentum  with  the  sinus  broadly  arcuate  at  the  bottom;  anterior  and 
middle  tarsi  (cf )  dilated  and  biseriately  squamulose.  Length  n- 
11.5  mm.  Texas  (Brownsville) iripennis  Schf. 

The  description  of  iripennis  is  drawn  from  the  original,  as  I  do 
not  know  the  species  in  actuality;  the  prothorax  is  apparently  much 
more  transverse  and  the  mentum  tooth  more  obsolete  than  in  the 
other  species,  but  it  seems  to  belong  to  the  present  genus;  the  basal 
joint  of  the  hind  tarsi  is  not  described.  In  a  strong  light  an  almost 
complete  solar  spectrum  is  displayed  on  the  elytra  of  dichrous, 
where  the  strigilation  producing  the  play  of  color  is  rather  stronger 
than  in  the  others,  although  it  is  very  distinct  and  characteristic  in 
all  of  them.

Tribe  SELENOPHORINI. 

In  this  tribe  each  elytron  invariably  has  three  series  of  setigerous 
punctures  or  fovese,  usually  closely  adjacent  to  striae  2-5-7,  as  m 
Philodes  of  the  Acupalpini;  I  know  of  no  instance  where  there  are 
less  than  three  series;  in  the  Acupalpini,  however,  there  is  a  genus 
having  but  one  series  and  in  Stenomorphus  there  are  two  series  on 
each  elytron ;  the  mentum  is  usually  edentate  and  the  ligula  slender. 
The  genera  known  to  me  may  be  denned  as  follows: 

Basal  joint  of  the  hind  tarsi  notably  long  as  in  Pteropalus  of  the  Harpalini ; 
lateral  line  of  elytral  foveae  always  widely  interrupted 2 

Basal  joint  short,  as  in  most  species  of  Harpalus,  the  basal  joints  dimin- 
ishing slowly  in  length;  lateral  line  of  fovese  not  interrupted 9 

2 — Middle  tibiae  (cf)  not  arcuate,  the  anterior  tarsi  always  and  the 
intermediate  generally  though  not  always  dilated — as  for  example 
in  Selenophorus  riparms 3 

Middle  tibiae  (c?)  always  arcuate,  with  its  inner  margin  serratulo-den- 
ticulate 

3 — Basal  joint  of  the  anterior  tarsi  not  peculiarly  modified 4 

Basal  joint  greatly  enlarged,  especially  in  the  female,  as  noticeable  also 
as  a  reversional  character  in  some  of  the  Anisodactylini  (Gynan- 
drotarsus) 7 

4 — Hind  tarsi  very  slender,  nearly  as  long  as  the  tibiae  and  always  with 
fine  sparse  hairs  on  the  upper  surface;  dorsal  surface  of  the  body  more 
or  less  depressed  as  a  rule 5 

Hind  tarsi  always  much  shorter  than  the  tibiae,  the  abbreviation  of  joints 
2-4  generally  especially  apparent,  their  upper  surface  usually  more 
closely  and  evidently  puberulent 6 

5 — Body  oblong-oval,  the  elytra  frequently  opalescent  and  sometimes 
with  fine  sparse  diffused  punctulation;  never  opaque  in  the  female; 
ligula  slender,  generally  a  little  shorter  than  the  paraglossae,  which 
are  rather  broad  and  obliquely  subtruncate  at  tip;  labial  palpi 
usually  somewhat  stout,  with  the  second  and  third  joints  equal  in 
length.  North  and  South  America.  [Type  Selenophorus  opalinus 
Lee.] Hemisopalus 

Body  oval  or  elliptical,  with  Celia-like  habitus;  ligula  slightly  shorter 
than  the  paraglossae,  which  are  long  and  slightly  diverging;  third 
palpal  joint  a  little  shorter  than  the  second.  Atlantic  and  Gulf 
coasts  of  North  America Celiamorphus 

6 — Body  Harpalus-Yike  in  habitus,  generally  strongly  convex;  prothorax 
never  cordiform,  the  base  never  narrower  than  the  apex;  elytra 
with  the  series  of  punctures  usually  regular  and  adherent  to  the  striae, 
as  in  the  two  preceding  genera,  rarely  if  ever  opalescent,  the  scutellar 
stria  distinct;  ligula  about  as  long  as  the  paraglossae,  which  diverge 
slightly  at  apex;  second  and  third  joints  of  the  labial  palpi  slender 
and  subequal  in  length,  the  third  gradually  acuminate.  North  and 
South  America.  [Type  Carabus  palliatus  Fabr.  (impresses  Dej.)].

small  squamules;  integuments  always  dark  in  color.  North  America,

Hemisopalus  n.  gen. 

In  this  genus,  which  will  include  a  considerable  proportion  of 
the  species  previously  placed  in  Selenophorus  by  Putzeys,  LeConte, 
Bates  and  others,  we  occasionally  observe  fine  punctures  pervading 
the  entire  elytra,  but  they  never  have  the  character  so  notably 
developed  in  Athrostictus  Bates.  The  species  at  present  in  my 
collection  may  be  defined  as  follows: 

Hind  angles  of  the  prothorax  rounded 2 

Hind  angles  not  obviously  rounded,  though  sometimes  very  obtuse.  .  .8 

2 — Elytra  with  strong  and  very  evident  prismatic  iridescence 3 

Elytra  without  pronounced  iridescence,  though  very  shining  and  some- 
times with  submetallic  lustre;  upper  surface  much  more  convex.  .6 
3 — -Larger  species  7-10  mm.  in  length,  elytra  with  more  or  less  sparse 

but  obvious  suffused  punctulation  throughout 4 

Small  species,  not  over  6  mm.  in  length  and  of  very  depressed  form,  the 

suffused  punctulation  obsolete 5 

4 — Form  oblong,  very  moderately  convex,  black,  polished  in  both  sexes 
throughout,  the  margins  of  the  pronotum  finely  testaceous  and  the 
elytra  with  obvious  iridescence,  the  under  surface  black,  with  feeble 
metallic  glint;  legs  and  cephalic  appendages  pale  testaceous;  head 
rather  short,  with  well  developed  and  prominent  eyes,  the  foveae 
extremely  minute  and  feeble,  the  antennae  very  slender;  prothorax 
one-half  wider  than  long,  the  sides  subparallel,  evenly  and  moder- 
ately arcuate,  the  apex  sinuate,  with  rather  advanced  though  rounded 
angles  and  much  narrower  than  the  base,  which  is  transverse  and 
finely  margined,  with  obtuse  and  evidently  rounded  angles;  surface

The  descriptions  of  discoderoides  and  subtinctus  are  drawn  from 
the  originals;  the  latter  is  evidently  allied  to  delumbis  but  differs 
in  several  characters  besides  size,  as  may  be  noted  by  comparing 
the  descriptions.  The  following  species  does  not  seem  to  be  repre- 
sented in  my  collection: 

H.  iripennis  Say  (Har pains) — Body  black,  dark  piceous  beneath,  the 
antennae,  labrum,  mouth  and  legs  rufo-testaceous,  the  latter  paler; 
prothorax  somewhat  wider  than  long,  widest  in  the  middle,  hardly 
narrower  at  base  than  at  tip,  the  lateral  edge  piceous,  almost  regularly 
arcuated,  the  angles  obtusely  rounded,  the  basal  edge  rectilinear;  dorsal 
and  basal  lines  obsolete;  base  with  numerous  slight  punctures;  elytra 
blackish,  with  blue  and  iridescent  reflections.  Length  6.2  mm.  Locality 
not  given. 

It  is  said  by  LeConte  that  Selenophorus  varicolor  Lee.,  is  identical; 
it  is  described  as  follows : 

Oblong,  black,  very  shining;  head  smooth,  the  impressions  almost 
wanting,  the  mouth,  antennae,  palpi  and  legs  rufo-testaceous;  prothorax 
half  wider  than  long,  subquadrate,  feebly  emarginate  at  apex,  the  sides 
strongly  rounded,  feebly  converging  posteriorly,  the  hind  angles  obtuse, 


HARPALIN/E  141 

broadly  rounded,  the  base  very  feebly  emarginate;  surface  almost  flat, 
the  transverse  impressions  almost  wanting,  the  stria  extremely  fine, 
entire,  the  foveae  broad,  very  shallow,  finely  punctate;  elytra  slightly 
wider  than  the  prothorax,  parallel,  rounded  behind,  with  viridi-cyaneous 
reflections,  striate,  the  scutellar  stria  long  and  distinct;  intervals  nearly 
flat,  the  series  inconspicuous,  the  marginal  series  broadly  interrupted  at 
the  middle.  Length  6.5  mm.;  width  2.7  mm.  Pennsyvlania  and 
Georgia. 

From  this  evidence  I  think  there  can  be  no  doubt  that  varicolor 
Lee.,  is  truly  a  synonym  of  iripennis  Say,  and  depressulus  of  the 
above  table  is  evidently  closely  allied,  but,  as  the  thoracic  stria 
is  by  no  means  entire,  the  size  somewhat  smaller,  the  apical  elytral 
sinus  probably  deeper  and  the  geographic  habitat  quite  different— 
at  the  same  time  considering  the  multiplication  of  allied  species 
in  the  warmer  parts  of  the  country, — I  am  disposed  to  leave  it  as 
announced  for  the  present.  The  matter  seems  to  be  settled  in 
favor  of  this  course  by  Dr.  Horn,  who  states  (Proc.  Am.  Phil.  Soc., 
1880,  p.  182)  that  in  iripennis  the  hind  angles  of  the  prothorax 
are  distinct  but  obtuse  and  that  there  are  a  few  fine  punctures  in 
the  vague  basal  impressions,  and  further  that  the  elytra  are  scarcely 
sinuate.  In  depressulus  the  hind  angles  are  broadly  rounded,  the 
punctuation  of  the  latero-basal  parts  distinctly  dense  and  the  elytral 
sinus  deeper  and  more  obvious  than  in  any  other  species. 

Celiamorphus  n.  gen. 

Although  not  differing  by  any  decisive  structural  characters  from 
the  preceding  or  from  Selenophorus,  it  seems  fitting  to  separate 
the  small  elliptical  subdepressed  species  allied  to  ellipticus  Dej., 
as  a  distinct  genus,  because  of  their  different  habitus  and  opaque 
integuments,  at  least  in  the  female,  these  sexual  differences  being 
unknown  apparently  in  either  of  those  genera.  The  prosternal 
process  is  narrow,  horizontal  and  very  strongly  margined  through- 
out, and  the  hind  tarsi  are  very  long.  The  species  are  compara- 
tively few  in  number  and  rather  closely  allied  among  themselves. 
By  the  descriptions  of  Dejean  I  am  unable  to  separate  the  granarius 
and  pulicarius  of  that  author  from  his  ellipticus  and  so  have  ar- 
bitrarily affixed  these  names  to  a  rather  inharmonious  series  taken 
in  the  Atlantic  region,  whence  the  types  of  that  author  probably 
came.  There  are,  however,  some  other  forms  that  seem  to  be 
distinct  and  I  would  arrange  them  as  follows:

The  above  characters  of  ovalis  Dej.,  are  selected  from  the  rather 
diffuse  original  description;  it  is  said  by  Horn  that  the  surface 
lustre  is  slightly  iridescent,  but  I  hardly  think  this  term  can  apply 
to  such  iridescence  as  is  observed  in  the  preceding  genus,  and  it  is 
not  alluded  to  by  Dejean  in  his  description. 

Selenophorus  Dej. 

As  a  group  of  the  Selenophorids,  this  genus  is  well  distinguished 
from  either  of  the  preceding  by  the  much  more  convex  form  of  the 


HARPALIN/E  145 

body,  with  prevalence  of  cupreous  or  aeneous  lustre  and  in  the 
much  shorter  hind  tarsi;  this  is  particularly  noticeable  in  the  more 
typical  forms,  such  as  palliatns  Fabr.,  where  the  tarsi  become  very 
much  stouter  than  usual,  with  joints  2-4  much  abbreviated  and 
together  but  little  longer  than  the  first  joint;  although  in  smaller 
forms,  such  as  fatuus,  the  tarsi  become  slender,  they  are  always 
distinctly  shorter  than  the  tibiae.  The  prosternal  process  more 
resembles  that  of  Hemisopahis,  being  broader  than  in  the  preceding 
genus,  less  horizontal  and  not  margined.  The  upper  surface,  so 
far  as  known  to  me,  never  becomes  suffusedly  punctulate  as  in 
many  species  of  Hemisopahis,  or  opaque  in  either  sex  as  in  Celia- 
morphus.  The  species  are  rather  numerous,  those  at  present  in 
my  collection  being  as  follows: 

Larger  species,  never  under  6  mm.  in  length 2 

Small  species,  with  about  6  mm.  as  their  superior  limit  of  length;  scutel- 

lar  stria  short  and  generally  feeble .6

aeneous  reflection  throughout  above,  piceous-black  and  without 
metallic  lustre  beneath,  the  legs  short  and  stout,  testaceous;  head 
rather  large,  more  than  three-fifths  as  wide  as  the  prothorax,  with 
well  developed  prominent  eyes  and  distinct  deep  sublinear  foveae; 
antennae  slender,  obscure  testaceous,  gradually  paler  basally,  the 
palpi  testaceous;  prothorax  large,  subparallel,  only  about  two-fifths 
wider  than  long,  rounded  at  the  sides,  which  become  straight  and 
barely  converging  behind  the  middle,  the  apex  feebly  sinuate  and 
much  narrower  than  the  base,  the  latter  broadly  and  distinctly 
sinuate  medially,  with  the  angles  scarcely  more  than  right  and  nar- 
rowly blunt  at  their  tips;  surface  evenly  convex,  very  finely,  evenly 
reflexed  at  the  sides,  impunctate,  the  foveae  broadly  sublinear  but 
extremely  feeble,  the  stria  fine  but  subentire;  elytra  oblong,  not 
quite  one-half  longer  than  wide,  the  apices  strongly  oblique  but  not 
sinuate,  the  tips  acute,  equal  in  width  to  the  prothorax;  striae  very 
fine,  the  scutellar  fine,  moderately  long,  the  intervals  flat,  the  surface 
near  the  posterior  part  of  the  sides  and  the  apex  with  suffused  punc-

The  remarkable  abdominal  sexual  characters  of  the  pedicularius

been  observed  hitherto;  they  are  entirely  wanting  in  planipennis 
and  maritimus,  very  feeble  in  honstoni  and  again  obsolete  in  ceneo- 
piceus,  showing  that  these  species  are  not  so  closely  associable  with 
pedicular itts  and  troglodytes  as  formerly  supposed.  They  were  not 
discovered  by  the  writer  until  the  descriptions  of  the  species  given 
above  had  been  long  under  way,  and,  as  the  species  having  like 
sexual  characters  happen  to  be  brought  into  juxtaposition  by  use 
of  other  more  general  characters,  it  is  not  necessary  to  recast  the 
table  on  that  score.  As  another  interesting  fact,  pointing  toward 
Discoderus,  it  should  be  stated  that  in  riparius  the  middle  tarsi  of 
the  male  are  completely  undilated  and  very  slender,  though  bearing 
beneath  the  usual  two  series  of  squamules. 

Beauvoisi  Dej.,  is  of  a  common  Central  American  type  and  has 
occurred  so  far  only  in  the  West  Indies.  The  following  species  is 
decidedly  doubtful  as  to  generic  relationship,  so  far  as  published 
characters  serve  to  show: 

S.  breviusculus  Horn — Oval,  slightly  oblong,  robust,  piceous,  the 
legs  pale;  surface  feebly  shining,  with  distinct  bronze  lustre;  head  punc- 
tulate,  rugulose  at  the  sides  above  the  eyes;  prothorax  broad,  the  apex 
and  base  equal,  the  sides  rather  strongly  arcuate;  basal  angles  broadly 
rounded,  the  base  feebly  emarginate  at  the  middle;  surface  convex, 
the  sides  slightly  depressed  posteriorly,  more  shining  at  the  middle, 
finely,  transversely  wrinkled,  in  front  finely  punctulate,  at  base  and  sides 
densely  punctate  and  opaque;  elytra  not  wider  than  the  prothorax, 
scarcely  a  third  longer  than  wide,  the  sides  moderately  arcuate,  the  apex 
scarcely  at  all  sinuate,  moderately  deeply  but  finely  striate,  the  inter- 
vals flat  and  irregularly  but  finely,  biseriately  punctulate  and  pubescent; 
serial  punctures  very  fine  and  indistinct;  eighth  stria  distant  from  the 
margin;  body  beneath  feebly  shining,  the  abdomen  sparsely  punctate 
and  with  short  pubescence;  legs  testaceous,  the  middle  and  posterior 
tibiae  slightly  arcuate.  Length  6.5  mm.  Indian  Territory  (now  Okla- 
homa),— Fort  Cobb. 

I  have  seen  no  representative  of  this  species,  but  it  is  my  opinion 
at  present  that  it,  together  with  curvipes,  arcuatus  and  crassiusculus, 
should  be  separated  as  a  distinct  genus,  coming  between  Seleno- 
phorns  and  Discoderus. 

Selenalius  n.  gen. 

The  general  habitus  of  this  genus  is  quite  distinct  from  that 
observable  elsewhere  in  the  Selenophorini,  due  to  the  peculiar  shape 
of  the  prothorax,  which  recalls  that  of  Glanodes.  Presumably  not

knowing  the  male,  Dr.  Horn  placed  the  type  species  in  Discodertis. 
The  head  is  well  developed,  the  mentum  completely  edentate  as 
usual  and  the  frontal  fovese  more  obvious  than  usual.  The  hind 
tarsi  are  short  as  in  Selenophorus,  but  the  basal  joint  is  not  quite 
so  elongate,  being  scarcely  longer  than  the  next  two  joints  com- 
bined. A  rather  singular  character,  partially  presaged  in  Seleno- 
phorus fatuus,  is  the  freedom  of  the  punctures  of  the  elytral  series 
from  the  striae;  the  punctures  of  the  two  inner  series  are  but  seldom 
in  close  contact  with  the  strije,  though  they  are  nearly  normal  and 
substrial  in  the  outermost  series;  in  fatuus  it  is  the  middle  series 
that  is  notably  erratic.  My  material  seems  to  indicate  two  species 
as  follows: 

Form  suboblong,  rather  elongate,  very  moderately  convex,  strongly 
shining,  dark  testaceous  throughout,  except  the  elytra,  which  are 
blackish-piceous  and  with  scarcely  visible  greenish  metallic  lustre; 
head  fully  three-fourths  as  wide  as  the  prothorax,  with  moderate 
though  very  prominent  eyes,  the  foveae  small  and  deep,  punctiform 
and  lying  within  rather  deep  impressions;  antennae  pale  testaceous, 
slender  and  rather  long;  prothorax  one-half  wider  than  long,  the 
sides  strongly  rounded  anteriorly,  becoming  oblique  and  nearly 
straight  thence  to  the  base  and  finely  though  strongly,  evenly 
re  flexed  throughout;  base  transverse,  slightly  arcuate  laterally, 
with  the  angles  very  obtuse  but  evident  though  distinctly  blunt, 
not  three-fourths  as  wide  as  the  apex,  which  is  broadly  and  very 
feebly  sinuate;  surface  with  feeble  transverse  rugulae,  fine  but  distinct 
subentire  stria  and  rather  evident  traces  of  irregular  anterior  and 
posterior  transverse  impressions,  the  fovese  moderate  in  size,  deep 
toward  base  and  with  a  fewr  feeble  sparse  punctures;  elytra  one-half 
longer  than  wide,  a  third  wider  than  the  prothorax,  nearly  parallel, 
with  feebly  arcuate  sides,  widely  basally  exposed  and  non-denticulate 
humeri  and  obtusely  ogival  apex,  the  sinus  obsolete;  striae  fine  [but 
rather  deep,  the  scutellar  nearly  obsolete,  the  intervals  flat  except 
at  apex,  the  serial  punctures  small  and  feeble,  the  margins  and  apex

rower, t  ully  one-half  longer  than  wide,  nearly  as  in  cordicollis  but 
more  evenly  parabolically  rounded  at  apex,  with  the  humeri  less 
broadly  exposed  basally  and  the  striae  a  little  coarser  and  more 
impressed,  with  feebly  convex  intervals,  especially  suturally,  the

This  genus  seems  to  be  confined  to  the  Sonoran  fauna  and  the 
species  are  probably  rather  local  in  distribution. 

Gynandropus  Dej. 

The  Anisodactylides  of  Lacordaire,  to  which  group  Gynandropus 
is  referred  by  that  author,  are,  as  shown  by  knowledge  of  the 
present  day,  the  receptacle  of  many  discordant  elements,  of  which 
the  present  genus  is  one  of  the  most  obscure  in  its  relationships. 
It  is  true  that  the  tarsal  vestiture  of  the  male  is  rather  solid,  but 
careful  observation  proves  it  to  be  seriately  squamiform  and  not 
uniformly  spongiose,  and  the  fact  that  the  female  tarsi  are  also 
partially  clothed  beneath,  together  with  the  peculiar  habitus  of  the 
body,  shows  that  it  cannot  be  closely  associated  with  any  other 
known  genus.  The  large  basal  joint  of  the  female  anterior  tarsi 
betrays  at  least  some  affinity  with  Stenomorplms  and  the  general 
habitus  of  the  body  and  presence  of  three  series  of  setigerous  elytral 
punctures  indicates  a  relationship  with  Selenophorus  and  Discoderus. 

In  the  male  of  Gynandropus  both  the  anterior  and  middle  tarsi 
are  stout  and  densely  clothed  beneath,  evenly  throughout  the 
length  of  the  first  four  joints,  with  white  squamiform  vestiture  in 
two  absolutely  contiguous  series,  so  that  the  soles  are  uniformly 
clothed  throughout,  the  texture  of  the  squamae  transverse  in 
structure.  The  basal  joint  is  only  moderately  enlarged,  the  first 
four  joints  decreasing  almost  uniformly  in  size  and  nearly  similar 
in  form,  the  intermediate  but  little  less  stout  than  the  anterior  and 
otherwise  similar.  In  the  female  the  basal  joint  of  the  anterior 
tarsi  is  relatively  very  large,  oblong-oval,  much  longer  than  the 


156  MEMOIRS  ON  THE  COLEOPTERA 

next  two  joints  combined  and  very  much  broader,  almost  as  in 
Stenomorphus,  though  not  nude  beneath  as  in  that  genus;  the 
middle  tarsi  are  nearly  like  the  anterior  but  less  dilated  throughout. 
The  large  basal  joint  of  the  anterior  is  broadly  and  feebly  concave 
beneath  and  uniformly  and  densely  clothed  with  very  short  slender 
squamae;  on  the  second  joint  these  become  longer  and  less  dense, 
though  similarly  confused  in  arrangement,  and  on  the  third  they 
become  still  longer,  finer  and  criniform,  sparse  and  with  their  apices 
apparently  sensitive.  The  middle  tarsi  have  the  basal  joint  large 
but  much  less  dilated  than  that  of  the  anterior  and  more  strongly 
squamose  beneath,  the  squamae  more  biseriately  arranged,  some- 
what as  in  the  male,  though  much  less  evidently  so  on  joints  two 
to  four.  It  will  be  noted  that  these  characters  are  most  exceptional. 
The  two  species  known  within  our  faunal  limits  may  be  described 
as  follows: 

Form  elongate,  polished,  convex,  deep  black  above,  without  trace  of 
metallic  lustre,  piceo-rufous  beneath,  the  legs,  antennae,  labrum 
and  oral  organs  pale  testaceous;  head  nearly  three-fourths  as  wide  as 
the  prothorax,  with  rather  large  and  prominent  eyes,  the  antennae 
slender,  filiform  and  extending  far  behind  the  thoracic  base;  labrum 
barely  at  all  sinuate  medially,  with  broadly  rounded  angles;  frontal 
impressions  small,  deep  and  punctiform,  nearly  as  in  Discoderus; 
prothorax  but  very  slightly  wider  than  long,  the  apex  and  base 
subequal,  truncate,  the  sides  rounded,  a  little  more  converging 
basally,  the  angles  very  obtuse  but  not  or  scarcely  rounded;  base 
finely  margined;  side  margins  very  finely  reflexed;  surface  smooth 
and  polished,  more  feebly  declivous  but  scarcely  explanate  and  with 
numerous  coarsish  punctures  latero-basally,  the  foveae  shallow; 
median  stria  very  fine,  the  transverse  impressions  shallow  and  very 
vague;  elytra  three-fifths  longer  than  wide,  fully  a  third  wider  than 
the  prothorax  and  about  three  times  as  long,  parallel,  obtusely 
rounded  at  tip,  the  apices  narrowly  oblique  though  barely  visibly 
sinuate;  striae  rather  fine  but  deeply  and  broadly  impressed,  the 
scutellar  wholly  wanting,  the  fovea  however  large  and  distinct,  the 
striae  shallower  and  sometimes  feebly  punctulate  laterally;  intervals 
convex,  especially  suturad;  setigerous  punctures  of  striae  2-5-7 
obvious;  lateral  line  of  foveae  broadly  interrupted;  legs  rather  short 
and  slender;  basal  joint  of  the  hind  tarsi  much  longer  than  the  next 
two  as  in  Discoderus.  Length  (c?  9  )  6.0-7.0  mm.;  width  2.2-2.5 
mm.  Rhode  Island,  New  Jersey,  Staten  Island  and  Catskill  Mts. 
[G.  americanus  Dej.;  Harpalus  hylacis  Say] hylacis  Say 

Form  narrower  than  in  the  preceding,  black,  shining;  head,  antennae  and 
palpi  similar,  the  legs  rufous;  prothorax  not  shorter  than  wide, 
truncate  at  apex  and  base,  the  sides  rounded,  the  hind  angles  slightly 
explanate,  obtuse,  somewhat  rounded;  surface  convex,  the  transverse

impressions  obsolete,  the  longitudinal  stria  fine,  abbreviated  at  both 
ends,  the  basal  foveae  small,  punctate;  elytra  slightly  wider  than  the 
prothorax,  almost  three  times  as  long  as  wide,  parallel,  moderately 
rounded  at  tip,  striate;  striae  2-5-7  with  rather  distinct  series  of 
punctures;  intervals  smooth,  slightly  convex.  Length  6.2  mm.; 
width  1.8  mm.  Georgia elongatus  Lee. 

The  description  of  elongatus  is  taken  from  the  original;  it  is  said 
to  be  very  rare;  hylacis  however,  is  frequently  taken,  although  not 
very  common.  The  head  does  not  differ  much  sexually,  but  if 
anything  is  a  trifle  larger  in  the  female  than  in  the  male. 

Discoderus  Lee. 

The  genus  Discoderus  is  represented  by  numerous  species  through- 
out the  temperate  parts  of  North  America  but  is  wanting  in  the 
true  Pacific  coast  fauna.  The  body  is  oblong,  rather  strongly 
convex  as  a  rule,  glabrous,  the  mental  sinus  edentate,  the  ligula 
rather  short  and  narrow,  the  paraglossse  much  exceeding  it  in 
length,  wide,  thick  and  rounded  at  their  apices,  the  palpi  normally 
slender,  the  second  joint  of  the  labial  with  about  three  long  and 
several  short  setae  and  equal  in  length  to  the  third,  making  therefore 
somewhat  of  an  approach  to  the  second  section  of  the  subfamily 
in  this  respect.  The  frontal  foveae  are  very  small  and  isolated,  not 
linear,  the  mandibles  and  eyes  moderate  and  the  antennae  slender 
but  not  unusually  long.  The  hind  angles  of  the  prothorax  are 
invariably  rounded,  the  elytral  striae  more  or  less  fine,  the  second, 
fifth  and  seventh  with  a  series  of  small  setigerous  punctures,  the 
outer  series  of  foveae  broadly  interrupted  as  a  rule  and  the  scutellar 
stria  distinct.  The  two  anterior  tarsi  of  the  male  are  scarcely  at 
all  dilated  and  have  two  series  of  minute  inconspicuous  squamules 
beneath.  Our  species,  which  are  frequently  closely  allied  among 
themselves,  may  be  described  as  follows: 

Prothorax  more  strongly  transverse,  nearly  one-half  wider  than  long. 
Form  parallel,  rather  convex,  shining,  black,  with  subaeneous  or 
feeble  viridi-aeneous  lustre,  the  under  surface  and  legs  blackish- 
piceous,  the  antennae  ferruginous;  head  nearly  two-thirds  as  wide 
as  the  prothorax,  the  slender  antennae  extending  well  behind  the 
latter,  which  is  parallel  and  evenly  arcuate  at  the  sides,  with  very 
broadly  rounded  basal  angles,  the  base  medially  feebly  bisinuate; 
surface  with  shallow  subpunctiform  basal  foveae,  behind  which  and 
near  the  sides  there  are  some  evident  punctures;  basal  stria  entire, 
the  margin  thicker  medially;  median  stria  fine  but  distinct;  elytra

hesperus  n.  sp. 

The  species  named  parallelus  Hald.,  above,  is  the  one  usually 
identified  as  Selenophorus  parallelus  of  that  author,  but  the  original 
description  (Pr.  Acad.  Phila.,  I,  1843,  p.  301)  does  not  agree  very 
well;  this  is  as  follows: 

Lengthened  oval,  black,  shining;  antennae,  palpi,  tibiae  and  tarsi 
rufous;  femora  darker  or  chestnut;  head  glabrous;  posterior  impressions 
of  the  pronotum  slight  and  minutely  rugose;  elytra  slightly  sinuate, 
striate;  striae  alternately  obsoletely  punctured,  a  row  of  about  6  punctures 
upon  the  inner  edge  of  the  3d  insterstice.  8  mill.  long.  Larger  and 
narrower  in  comparison  than  S.  ellipticus,  with  the  sides  of  the  elytra 
more  nearly  parallel  and  the  abbreviated  stria  near  the  scutel  more 
distinct. 

No  locality  is  given  under  the  descripton,  but,  as  the  species  is 
listed  in  a  catalogue  of  the  Coleoptera  of  southeastern  Pennsyl- 
vania, preceding  in  the  same  paper,  it  is  to  be  assumed  that  the 
species  is  from  that  region.  The  length  is  materially  greater  than 


164  MEMOIRS  ON  THE  COLEOPTERA 

that  of  any  Atlantic  coast  form  of  Discoderus  known  to  me,  and 
the  sinus  of  the  elytra  could  hardly  be  described  even  as  slight;  it 
is  the  merest  vestige,  which  would  be  unobservable  unless  looked 
for  very  sharply. 

In  Bull.  Mosc.  1859,  p.  137,  Motschulsky  describes  a  Pangus 
americanus,  which  is  evidently  a  Discoderus  and  it  is  correctly 
assigned  to  that  genus  in  the  Munich  catalogue.  The  type  was 
given  to  the  describer  by  Dupont,  as  coming  from  California,  but, 
as  the  genus  Discoderus  does  not  seem  to  occur  in  California,  the 
Dupont  specimen  was  in  all  probability  incorrectly  labeled  and 
might  have  been  from  almost  any  other  locality  in  North  America. 
As  Motschulsky 's  description  fits  parallelus  very  well,  I  think  there 
can  be  no  lack  of  propriety  in  assigning  it  as  a  synonym  of  that 
species  as  proposed  above. 

Horn  describes  the  prothorax  of  robustus  (Bull.  Bk.  Ent.  Soc., 
VI,  p.  52)  as  being  "distinctly  narrower  at  base  than  at  apex," 
which  could  only  be  the  result  of  an  optical  illusion;  the  prothorax 
is,  if  anything,  a  little  wider  at  base  than  at  apex,  though  the  two 
are  very  nearly  equal,  as  stated  in  the  table.  Pinguis  Csy.,  which 
was  united  with  robustus  by  Dr.  Horn,  is  a  very  different  species, 
having  the  prothorax  notably  narrowed  at  apex  and  with  the  forma- 
tion of  the  basal  margin  and  the  extent  of  its  medial  sinuation 
altogether  at  variance  with  the  corresponding  characters  in  robustus. 
Piceus,  of  the  table,  is  held  to  have  a  value  at  least  subspecific, 
because  of  the  differences  stated,  which  are  quite  apparent  in  series; 
robustus  seems  to  be  much  more  constantly  deep  black  above  and 
piceous-black  beneath.  The  presence  of  fine  suffused  setigerous 
punctuation  at  the  sides  and  apex  of  the  elytra  in  most  of  the 
species  of  this  genus  does  not  seem  to  have  been  noted  heretofore; 
this  feature  is  similar  to  that  observed  in  the  genus  Selenophorus, 
indicating  another  bond  of  affinity.  It  will  also  be  observed  that 
the  head  is  distinctly  larger  in  the  female  than  in  the  male  in  many 
species,  as  in  Stenomorphus.  The  descriptions  of  crassicollis  and 
tenebrosus  are  taken  from  the  originals,  as  I  do  not  have  these 
species  at  hand. 

The  genus  Trichopselaphus  Chd.,  has  some  peculiar  male  sexual 
characters,  the  arcuation  of  the  hind  tibiae  in  that  sex  being  analo- 
gous to  the  similar  arcuation  of  the  intermediate  tibiae  in  Discoderus, 


HARPALIKLE  165 

but  here,  in  addition,  the  hind  femora  are  inflated  and  strongly 
dentate  beneath  and  the  anterior  tarsi  are  rather  broadly  dilated 
and  clothed  beneath  with  conspicuous  squamules.  The  type 
species  is  Trichopselaphus  subiridescens  Chd.,  of  southern  Brazil. 
Its  relationship  with  Gynandropus  and  Stenomorphus  is  distinctly 
indicated  by  the  form  of  the  female  anterior  tarsus,  where  the  basal 
joint  is  conspicuously  larger  than  any  of  the  following  joints.  La- 
cordaire  does  not  say  whether  the  elytra  are  triseriately  punctate 
as  in  Discoderus,  but  in  the  single  Mexican  species  described  by 
Bates,  T.  minor  Bates,  the  second,  fifth  and  seventh  striae  are  said 
to  be  inconspicuously  punctured  in  series.  Mr.  Bates  states  (Biol. 
Cent.-Amer.,  I,  i,  p.  62)  that  the  Venezuelan  genus  Anisocnemus 
Chd.,  belongs  in  this  vicinity,  being  especially  allied  to  Discoderus , 
but,  according  to  the  description  of  Lacordaire,  this  affinity  could 
only  be  surmised  from  the  dilatation  of  the  hind  femora;  in  the  very 
acute  basal  angles  of  the  prothorax  it  departs  widely  from  Disco- 
derus; there  may  however  be  a  closer  affinity  with  Trichopselaphus, 
though  this  seems  to  be  unsuspected  by  the  author  of  the  "Genera," 
who  places  the  genus  just  before  Harpalus. 

Hartonymus  n.  gen. 

That  so  conspicuous  and  aberrant  a  generic  type  should,  in  the 
thickly  settled  state  of  Illinois,  so  long  have  remained  undiscovered, 
is  merely  a  reminder  that  our  Coleoptera  are  still  only  known  in 
comparatively  small  part ;  the  peculiar  pallid  coloration  of  the  body 
gives  an  appearance  of  immaturity,  which  may  however  possibly 
have  led  many  a  collector  to  reject  it  as  undesirable  material— 
always  an  unsafe  procedure.  The  body  is  oblong,  subparallel  and 
strongly  convex,  with  broadly  rounded  basal  angles  of  the  pro- 
thorax,  so  that  in  every  way  except  color  it  closely  resembles  a  very 
large  Discoderus,  but  the  middle  tibiae  of  the  male  are  straight  and 
unmodified  and  the  anterior  and  middle  tarsi  of  that  sex  broadly 
dilated  and  strongly  biseriately  squamose  beneath,  exactly  as  in 
the  genus  Harpalus,  from  which  it  differs  in  having  three  series  of 
substrial  elytral  punctures  as  in  Discoderus  and  Selenophorus.  The 
ligula  is  broadest  and  rectilinearly  truncate  at  apex  and  equal  in 
length  to  the  moderate,  apically  obtuse  paraglossae,  and  the  mentum 
has  a  broad  and  sharply  triangular  tooth,  all  of  which  features  are 


1 66  MEMOIRS  ON  THE  COLEOPTERA 

again  exactly  as  in  Harpalus;  it  also  resembles  that  genus,  and 
departs  from  the  Selenophorini,  in  the  short  basal  joint  of  the  hind 
tarsi.  The  labial  palpi  are  as  in  Harpalus.  In  fact  the  only  strong 
evidences  of  affinity  in  the  direction  of  Selenophorus  are  the  triple 
series  of  elytral  punctures,  uniformly  punctate  abdomen,  and  the 
Discoderus-like  facies  of  the  body;  as  however  the  triple  series  are 
unknown  in  Harpalus  and  allied  genera,  it  would  seem  most  fitting 
to  place  the  genus  here  and  not  in  the  Harpalini.  This  genus  is 
the  best  example  known  to  me  of  the  almost  interminable  cross 
affinities,  which  render  a  satisfactory  subdivision  into  tribes  and 
genera  so  difficult  and  uncertain  throughout  the  Harpalinae.  The 
type  species  may  be  described  as  follows : 

Body  oblong-elongate,  strongly  convex,  shining,  the  elytra  (  9  )  slightly 
alutaceous;  color  pale  and  uniform  testaceous  throughout ;.  head 
nearly  two-thirds  as  wide  as  the  prothorax,  only  feebly  constricted 
at  base,  the  eyes  moderate,  the  foveae  minute  and  perforato-puncti- 
form;  mandibles  short,  largely  hidden  when  closed,  the  antennae 
moderately  stout,  as  long  as  the  thoracic  width,  or  shorter  (9); 
prothorax  one-half  wider  than  long,  slightly  widest  before  the  middle, 
the  sides  almost  evenly  and  broadly  arcuate;  apex  feebly  and 
sinuously,  the  base  rectilinearly,  truncate,  equal  in  width;  basal 
angles  broadly  rounded;  surface  impunctate,  steeply  sloping  at  the 
sides  to  the  rather  wide  subdeplanate  reflexed  margin  throughout 
the  length,  the  flattened  margin  curving  inward  at  base,  smooth  but 
having  four  long  erect  setae  arising  from  coarse  punctures;  stria 
extremely  fine,  the  foveae  small,  sublinear  and  deeply  impressed, 
wholly  impunctate;  elytra  oblong,  parallel,  with  feebly  arcuate  sides 
and  obtuse  apex,  equal  in  width  to  the  prothorax  and  fully  one-half 
longer  than  wide,  the  humeii  minutely  denticulate,  the  sinus  broad 
and  extremely  feeble,  the  apices  (cf)  rounded,  or  ( 9  )  with  acutely 
spiniform  sutural  angles,  the  denticles  bordered  externally  by  a  short 
deep  sinus,  this  structure  being  somewhat  as  in  Harpalus  leicisi; 
striae  rather  strong,  the  scutellar  very  moderate,  the  intervals  neaily 
flat,  slightly  convex  suturally,  nowhere  punctulate,  the  marginal  line 
of  foveae  not  medially  interrupted;  punctures  of  the  three  lines  coarse, 
widely  spaced  and  somewhat  erratic,  not  always  closely  connected 
with  the  striae,  this  being  especially  the  case  with  the  middle  series; 
abdomen  uniformly,  finely  and  sparsely  punctulate,  the  punctures 
bearing  erect  and  rather  stiff  short  hairs,  the  apex  with  four  setae 
in  both  sexes;  legs  rather  stout,  the  hind  tarsi  filiform,  moderately 
stout,  the  three  basal  joints  decreasing  uniformly  and  slowly  in 
length,  the  first  two-thirds  as  long  as  the  fifth,  the  claws  rather  long, 
slender  and  not  very  arcuate;  bristling  hairs  of  the  middle  and  hind 
tibiae  very  numerous;  tibial  spurs  short  and  stout,  the  single  spur  of 
the  anterior  with  a  distinct  angulation  at  one  side  near  the  base.

Aside  from  the  plurality  of  marginal  thoracic  setae,  in  which  it 
resembles  Nothopus,  Piosoma  and  the  Acupalpid  Glycerins  nitidus, 
the  triple  elytral  series  of  punctures  and  uniformly  punctulate 
abdomen,  in  which  it  resembles  Selenophorus  and  allied  genera  and 
the  peculiar  pallid  coloration  of  the  dense  integuments,  in  which  it 
perfectly  recalls  Geopinus  and  Pharalus — all  constituting  further 
examples  of  the  confusing  structural  parallels  previously  alluded 
to, — the  characters  of  this  genus  are  so  purely  Harpalid  that  it  forms 
a  very  strong  argument  in  favor  of  those  who  contend  against  the 
propriety  of  separating  Selenophorns  from  Harpalus.  In  such 
cases  there  are  only  two  courses  available  to  the  systematist: 
either  to  regard  all  as  forming  a  single  genus,  with  numerous  sub- 
generic  groups,  which  must  be  named  in  order  to  facilitate  refer- 
ence, or  to  consider  these  groups  as  genera.  For  nomenclatorial 
reasons  I  believe  the  latter  course  to  be  by  far  the  more  rational,  if 
warranted  in  any  way  by  structural  divergencies.  There  are 
numerous  instances  of  polymorphous  genera  of  this  kind  in  the 
Mollusca,  such  as  Pleurotoma  and  Pyramidella. 

Tribe  STENOMORPHINI. 

There  is  but  a  single  genus  assignable  to  this  tribe,  one  of  the  most 
isolated  types  of  the  subfamily  as  follows: 

Stenomorphus  Dej. 

While  the  radical  departure  in  habitus  of  this  genus  from  the 
others  warrants  a  rather  wide  separation  from  more  normal  forms 
of  the  subfamily,  it  is  none  the  less  truly  a  member  of  the  Har- 
palinae  in  all  structural  features,  and  its  assignment  to  the  Pogoninae 
by  Lacordaire  was  a  decided  error;  but,  in  the  early  days,  before 
the  discovery  of  criteria  afforded  by  the  supra-orbital  setae,  failure 
to  observe  true  relationships  was  quite  excusable.  The  under 
surface  of  the  male  tarsus  was  however  erroneously  figured  on 
Plate  XII  of  the  "Genera"  by  that  author,  joints  2-4  being  depicted 
as  uniformly  clothed  throughout  their  under  surface.  In  this  genus 
the  tarsi  are  of  a  peculiar  form,  though  recalling  in  their  most 
salient  features  those  of  Gynandropus.  In  the  male,  the  first  joint 


1 68  MEMOIRS  ON  THE  COLEOPTERA 

of  the  anterior  tarsi  is  not  much  dilated  but  long,  not  quite  equaling 
the  next  three  combined  and  evidently  wider  than  the  second, 
perfectly  nude  beneath;  joints  2-4  feebly  diminish  in  size  and 
have  beneath  two  series  of  large  and  upwardly  inclined  squamae, 
the  texture  of  which  is  longitudinal  and  quite  unlike  the  trans- 
versely strigose  squamae  of  Gynandropus  and  the  series  are  further- 
more evidently  separated  and  not  contiguous  as  they  are  in  that 
genus;  the  middle  tarsi  differ  scarcely  at  all  from  the  posterior,  but 
seem  to  have  a  few  feeble  and  scarcely  discernible  squamae  beneath 
joints  2-4,  amid  the  spiniform  hairs.  In  the  female,  the  first  joint 
of  the  anterior  and,  to  a  less  degree,  that  of  the  intermediate  tarsi, 
is  much  more  strongly  dilated  than  in  the  male,  oval,  narrowed 
basally  and  truncate  at  apex,  as  long  as  the  next  three  combined 
and  even  somewhat  more  than  twice  as  wide  as  the  second  on  the 
anterior  pair,  1-4  nude  beneath  but  with  short  sparse  spines, 
2-4  spinulo-setose  laterally  beneath  and  relatively  much  smaller 
than  in  the  male.  The  palpi  are  unusually  inflated,  the  last  joint 
of  the  labial  oval,  truncate  at  tip  and  bristling  with  setae  in  a  way 
not  so  noticeable  in  most  of  the  normal  genera.  The  mental  sinus 
is  edentate.  The  elytra  have  two  series  of  setigerous  punctures, 
at  the  second  and  fifth  striae,  which  do  not  seem  to  have  been 
observed  hitherto. 

The  species  are  rather  numerous,  those  known  to  me,  either  in 
nature  or  by  description,  being  as  follows: 

Posterior  tibiae  with  series  of  spinules,  the  anterior  with  a  fringe  of  coarse 
hairs  internally.  [Stenomorphus  in  sp.] 2

The  interesting  reversal  of  the  usual  sexual  characters  of  the 
Coleoptera  in  having  the  head  larger,  the  prothorax  broader  and 
the  special  sexual  characters  of  the  tarsi  more  developed,  in  the 
female  than  in  the  male,  as  shown  in  scolopax,  reveals  itself  re- 
peatedly in  this  subfamily.  In  many  species  of  true  Harpalus  I

have  observed  that  the  head  is  relatively  somewhat  larger  in  the 
female  than  in  the  male,  sometimes,  as  in  the  case  of  Harpalus 
viduus,  notably  larger. 

Tribe  ANISODACTYLINI. 

This  is  a  large  tribe  and  one  of  the  most  clearly  circumscribed  of 
the  subfamily.  The  body  is  oblong  and  more  or  less  stout  and 
convex,  the  anterior  and  middle  tarsi  of  the  male  having  dense 
homogeneous  pads  of  erect  squamiform  pubescence  beneath. 
Otherwise  there  is  considerable  variety  of  structure,  sculpture  and 
coloration.  The  terminal  spur  of  the  anterior  tibiae  is  remarkably 
diversified  in  form,  in  some  groups  being  slender  and  simple,  in 
others  subbasally  swollen  or  angulate  on  one  or  both  sides  to 
strongly  trifid,  but  the  form  of  this  spur  is  somewhat  misleading 
from  a  taxonomic  viewpoint  and  does  not  necessarily  indicate  the 
degree  of  generic  relationship.  I  have  however  found  some  other 
structural  features,  such  as  the  mentum,  ligula  and  paraglossae, 
to  be  of  very  decided  value,  the  division  of  those  generic  groups 
having  a  distinct  mentum  tooth  into  two  sections  according  to  the 
form  of  the  paraglossse,  for  example,  being  very  sharply  drawn  and 
devoid  of  ambiguity.  The  genera  are  numerous,  those  represented 
before  me  being  as  follows: 

Mentum  not  toothed 2 

Mentum  with  a  clearly  denned  angulate  tooth n 

2 — Basal  joint  of  the  hind  tarsi  more  elongate,  fully  as  long  as  the  next

4 — Ligula  increasing  moderately  in  width  apically,  the  tip  more  or  less 
evidently  expanded,  the  paraglossae  obtusely  prolonged  to  a  moderate 
degree  externally  at  apex;  elytra  and  abdomen  not  punctulate  or 
pubescent;  hind  angles  of  the  prothorax  sharply  denned  to  rather 

broadly  rounded;  hind  tarsi  long,  glabrous  above 5

angles  always  blunt,  at  least  at  their  tips;  basal  joint  of  the  hind  tarsi 
long,  equal  to  or  exceeding  the  next  two  combined;  ligula  less

widely   diverging;    body  large,  broad  and    subglabrous,  sombre   in 

coloration.     Atlantic  and  Gulf  regions Spongopus 

Paraglossae  with  the  slender  apices  not  widely  diverging;  body  small  in 
size,  densely  punctate  above  and  beneath,  pale,  with  large  obscure 
elytral  macula,  nearly  as  in  Gynandromorphus;  hind  angles  of  the 
prothorax  sharply  right,  with  an  erect  seta  as  in  Dicheirotrichus  and 
Trichocelliis,  the  second  labio-palpal  joint  long  and  with  very 
numerous  bristling  setae  as  in  typical  Anisodactylus.  Palsearctic 
regions *Diachromus 

The  genus  Dicheirotrichus,  which  was  placed  in  this  tribe  by 
Duval,  is  a  singularly  annectant  form.  The  tarsal  pads  of  the 
male  are  loose  and  rather  confused,  but  the  general  facies  of  the 
body  is  somewhat  as  in  the  Acupalpid  genus  Trichocellus .  The 
second  joint  of  the  labial  palpi  has  three  long  setae.  I  have  placed 
it  among  the  Acupalpids  rather  than  here.  The  European  genera 
introduced  for  comparative  purposes  in  the  above  table  are  all  so 
well  known  that  it  seems  unnecessary  to  dwell  more  upon  them, 
further  than  to  say  that  Hexatriclms  Tsch.,  seems  to  be  valid  as  a 
genus  rather  than  as  a  subgenus  of  Anisodactylus,  which  is  its 
present  position  in  the  recently  published  catalogue  of  Heyden; 
Reitter  and  Weise. 

Triplectrus  Lee. 
Gynandrotarsus  Laf. 

This  genus  has  been  united  with  Anisodactylus  in  modern  works, 
but  there  are  some  peculiarities  which  seem  to  show  that  it  can  be 
regarded  as  a  genus  with  a  good  deal  of  propriety.  Its  species  can 
always  be  recognized  at  once  by  the  strongly  trifid  anterior  tibial 
spur,  which  is  always  a  non-sexual  feature,  but  aside  from  this  there 
is  a  modification  of  the  anterior  female  tarsi  occurring  here  and 
nowhere  else  in  the  tribe — not  developed  in  all  the  species  it  is 
true,  but  clearly  defined  in  several,  such  as  harpaloides,  opaculus 
and  texanus; — this  is  the  lateral  dilatation  of  the  basal  joint,  a  very 
significant  character,  recalling  a  nearly  similar  modification  in 
Stenomorphus  and  Gynandropus.  Intervals  3-5-7  of  the  elytra 
have  in  all  the  species  a  few  serial  punctures  along  the  median  line 
of  the  interstice  at  apex,  exactly  as  in  Glanodes,  and  especially  in 
Piosoma  alternata;  this  is  another  puzzling  parallelism  and  a  char- 
acter which  is  not  observable  in  Anisodactylus.  The  basal  joint 
of  the  hind  tarsi  is  very  long,  often  scarcely  shorter  than  the  next

moderately  numerous  and  recognizable  as  follows:

ated from  the  flat  sides  by  a  feeble  convexity,  all  closely  punctate;

slightly  wider  than  the  prothorax,  one-half  longer  than  wide,  broadly 
ogival  at  apex,  the  sinus  broad  and  extremely  feeble,  almost  ves-

harpaloides    Laf. 

The  species  described  by  La  Ferte  as  harpaloides  is  singularly 
aberrant,  and  were  it  not  for  the  fact  that  the  swollen  basal  joint 
of  the  anterior  female  tarsi  is  exactly  reproduced  in  the  more  normal 
texanus  and  opaculus,  I  should  be  disposed  to  give  Gynandrotarsus 
generic  standing.  Carbonarius  is  also  a  remarkably  distinct  species, 
for  not  only  are  there  two  distinct  and  constant  post-medial  punc- 
tures on  each  elytron — a  fact  overlooked  by  Horn,  but  merely  a 
particular  stage  of  the  anterior  prolongation  of  the  apical  series  on 
the  third  interval  noticeable  in  all  the  species  of  the  rusticus  sec- 
tion,— but  the  prosternum  is  punctulate  and  pubescent  medially, 
as  well  as  the  median  part  of  the  abdominal  base.  The  epistoma 
has  two  punctures  at  each  angle  instead  of  the  usual  one,  buc, 
although  perhaps  not  so  inconstant  a  character  as  in  Harpalus 
viridiceneus ,  it  is  at  least  unreliable  here  also,  for  in  several  cases 
at  hand  there  are  three  punctures  instead  of  two.  The  species  of 
the  rusticus  section,  as  defined  above,  which  were  suppressed  by 
Horn,  seem  to  be  sharply  limited  and  amply  worthy  of  adoption. 

Anisodactylus  Dej. 
Aplocentrus  Lee. 

The  first  species  described  under  this  name  by  Dejean,  Carabus 
heros  Fabr.,  probably  differs  generically  from  binotatus,  which  I 
assume  to  be  the  type  of  the  genus.  The  peculiar  coloration  of 
the  body  and  disposition  of  the  discal  punctures  of  the  elytra  in 
heros,  indicate  that  it  should  not  be  associated  closely  with  binotatus, 
the  latter  being  perfectly  congeneric  in  every  way  with  all  of  our 
numerous  black  or  feebly  metallic  species,  and  binotatus  Fabr., 
ought  therefore,  in  view  of  numerical  preponderance,  to  be  con- 
sidered the  generic  type;  the  American  species  outnumber  the 
palaearctic  three  or  four  to  one. 

The  genus  Anisodactylus  is  very  well  defined  in  habitus  and  in 
several  structural  features.  The  slender  hind  tarsi,  with  elongate

basal  joint,  are  nearly  as  in  Triplectrus,  except  that  the  upper 
surface  is  not  completely  impunctate  and  glabrous  as  in  that 
genus  but  has  more  or  less  evident,  sparse  and  sometimes  rather 
strong  punctures  bearing  erect  pale  seise  and  the  basal  joint  is 
relatively  not  quite  so  long.  The  terminal  spur  of  the  anterior 
tibise  is  acute  and  generally  swollen  slightly  or  broadly  angulate 
on  one  side  or  at  least  asymmetrically  toward  base.  The  elytra 
also  differ  greatly  from  those  of  Triplectrus  in  never  having  more 
than  one  discal  substrial  puncture  and  in  having  no  vestige  of  the 
apical  series  of  punctures  on  intervals  3-5-7;  there  is,  however, 
sometimes  a  fine  suffused  punctulation  on  the  alternate  intervals 
at  apex,  homologous  with  that  so  well  developed  in  Anadaptus 
porosus  Mots,  and  pitychrous  Lee.  The  vertex  generally  has  a 
central  rufous  spot,  not  only  in  this  genus  but  several  others  of  the 
tribe,  which  spot  I  have  never  observed  in  Harpalus. 
The  numerous  species  may  be  outlined  as  follows: 

Anterior  tibial  spur  swollen  and  usually  obtusely  angulate  at  least  on  one 
side  near  the  base 2 

Anterior  tibial  spur  very  slender  and  simple;  body  small  in  size,  the 
surface  lustre  more  or  less  metallic.  (Aplocentrus  Lee.) 22 

2 — Color  deep  black  throughout  the  body  and  legs,  the  upper  surface 
never  having  a  trace  of  metallic  lustre 3 

Color  black,  the  tibiae  and  tarsi  piceous,  the  upper  surface  with  rather 
strong  but  varied  metallic  lustre.  Pacific  coast 21 

3 — Species  of  the  Atlantic  regions;  body  rather  stout  as  a  rule  and  with 
deeper  elytral  striae  except  in  furvus,  the  posterior  thoracic  angles 
frequently  somewhat  rounded;  head  about  half  as  wide  as  the 
prothorax  as  a  rule 4

The  species  described  by  LeConte  under  the  name  similis  (Ann. 
Lye.,  V,  p.  183)  I  cannot  identify.     The  description  is  as  follows: 

A.  similis  Lee. — Oblong,  "minus  convexus"  [the  species  immediately 
preceding  in  the  rather  depressed  consobrinus],  black,  the  head  slightly 
punctulate;  prothorax  punctulate,  one-half  wider  than  long,  not  narrowed 
posteriorly,  the  finely  depressed  margins  evanescent,  behind  the  middle; 
hind  angles  right,  the  base  slightly  impressed,  densely  punctulate;  elytra 
finely  striate,  the  intervals  almost  flat,  the  third  impunctate  [!];  first 
joint  of  the  antennae  rufo-piceous,  with  a  fuscous  macula.  Length  11.5 
mm.  Oregon. 

If  the  prothorax  is  really  not  at  all  narrowed  posteriorly,  and  the 
statement  that  the  hind  angles  are  right  tends  to  confirm  the 
language  of  the  description  in  that  respeci,  it  would  cause  similis 
to  depart  distinctly  from  any  other  species  known  to  me.  G.  H. 
Horn  states  that  both  similis  Lee.,  and  puncticollis  Chd.,  are 
synonyms  of  semipunctatus  Lee.,  though  the  latter  is  of  a  much 
more  recent  date  than  similis.  As  to  puncticollis  Chd.,  described 
as  coming  from  Vancouver  Island,  the  author  states  that  the  pro- 
thorax  in  the  male  type  is  punctured  throughout,  showing  that  it 
belongs  to  the  semipunctatus  section,  that  the  hind  angles  of  the 
prothorax  are  "  parfaitement  droits"  and  that  the  elytra  are  not 
at  all  punctulate.  As  the  alternately  punctulate  intervals  are  a 
very  obvious  feature  in  the  male  of  semipunctatus,  there  is  reason 
to  believe  that  puncticollis  cannot  be  that  species,  and  it  is  my  belief 
that  it  is  a  synonym  of  similis  Lee.  There  is  also  reason  to  believe 
that  similis  is  a  valid  species,  with  virtually  parallel  sides  of  the 
prothorax,  and  not  very  closely  related  to  semipunctatus.  I  think 


HARPALIN/E  193 

that  the  statement  that  the  third  interval  is  impunctate  is  clearly  a 
misprint  for  unipunctate.  The  same  mistake  occurs  in  the  original 
description  of  confusus,  which,  from  the  published  characters  and 
the  note  of  its  abundance  at  San  Francisco,  must  be  identical  with 
californicus,  in  which  I  have  seen  no  instance  in  a  large  series 
where  the  discal  puncture  is  wanting.  In  fact  the  single  discal 
elytral  puncture  is  an  extremely  constant  feature  throughout  the 
genus.  In  lodingi,  which  is  unknown  to  me  in  nature,  this  important 
puncture  is  however  said  to  be  wanting;  that  species  is  aberrant 
also  in  its  great  size  of  body. 

Xestonotus  Lee. 

Some  question  has  been  raised  as  to  the  propriety  of  maintaining 
this  genus  distinct  from  Anisodactylus,  and  in  reality  it  is  very 
closely  allied,  but  there  is  a  rather  radical  departure  in  the  form  of 
the  ligula,  which,  considering  the  very  minute  punctiform  frontal 
fovese,  which  are  exactly  as  in  Harpalus,  complete  absence  of  the 
rufous  spot  on  the  vertex,  another  harpaloid  character,  broadly 
rounded  basal  angles  of  the  prothorax  and  very  posterior  posicion 
of  the  discal  elytral  puncture,  would  seem  to  warrant  its  retention, 
at  any  rate  as  not  less  than  a  very  well  marked  subgenus  of  Aniso- 
dactylus. The  only  known  species  is  the  following: 

Body  oblong,  stout,  moderately  convex,  deep  black  and  shining,  the 
elytra  (cf)  feebly  or  ( 9  )  strongly  alutaceous;  under  surface  and 
legs  throughout  deep  black;  head  rather  large,  two-thirds  as  wide 
as  the  prothorax,  the  eyes  very  moderate,  not  very  prominent; 
antennae  slender,  piceous,  the  basal  joint  pale;  surface  very  smooth, 
the  epistomal  suture  excessively  feeble,  sometimes  obsolescent;  ligula 
slender,  not  at  all  enlarged  at  apex,  the  paraglossae  fully  as  long  or 
somewhat  longer  and  very  obtuse  at  tip;  prothorax  short,  one-half 
to  three-fifths  (9)  wider  than  long,  the  sides  parallel,  evenly  and 
rather  strongly  arcuate;  apex  broadly  and  very  deeply  sinuate,  with 
advanced  though  rounded  angles  and  only  a  little  narrower  than 
the  base,  which  is  transverse,  rounding  laterally  toward  the  very 
broadly  rounded  angles;  surface  very  finely  reflexed  at  the  sides  in 
about  apical  half,  the  gutter  broadening,  becoming  feeble  and  dis- 
appearing at  basal  two-fifths  on  the  large  latero-basal,  finely  but 
densely  punctate  flattened  area,  the  foveae  large,  very  broad  and 
shallow,  with  some  coarser  punctures  in  addition  to  the  finer;  re- 
mainder of  the  disk  impunctate,  the  stria  fine,  entire  and  distinct; 
elytra  two-fifths  longer  than  wide,  parallel,  obtusely  rounded  at 
apex,  barely  visibly  wider  than  the  prothorax,  the  sides  feebly

arcuate;  sinus  feeble  but  distinct;  striae  nne/the  scutellar  long,  usually 
free;  intervals  flat  throughout  (9)  or  nearly  so  (cf),  the  entire 
surface  with  traces  of  excessively  minute  punctulation,  not  visible 
in  the  female,  the  lateral  line  of  fovese  subinterrupted  medially,  the 
discal  puncture  strong,  at  apical  fourth;  hind  tarsi  slender,  glabrous 
above,  the  first  joint  fully  as  long  as  the  next  two  and  much  longer 
than  the  fifth;  spur  of  the  anterior  tibiae  very  slender  and  simple. 
Length  (c?  9  )  10.0-10.8  mm.;  width  3.8-4.3  mm.  Rhode  Island  to 
Iowa.  Abundant.  [Selenophorus  lugubris  Dej.  (9);  Harpalus 
manhattanis  Csy.  (  9  )] lugubris  Dej. 

For  some  reason,  not  stated,  this  species  was  not  considered  by 
Dr.  Horn  in  his  sketch  of  Anisodactylns  (Proc.  Am.  Phil.  Soc., 
1880,  p.  162),  though  there  is  better  reason  for  considering  it  a 
part  of  that  genus  than  there  is  to  include  Dicheirus.  The  female 
type  was  placed  in  Selenophorus  by  Dejean,  solely  because  of  the 
very  slender  ligula  and  absence  of  mentum  tooth,  but  the  three 
series  of  elytral  punctures  constitute  a  more  decisive  generic  mark 
of  Selenophorus  than  the  structure  of  the  mouth  parts.  The  fact 
that  no  one,  observing  solely  the  female,  would  probably  think  of 
placing  the  species  in  Anisodactylus,  is  at  least  one  reasonable  proof 
of  its  generic  isolation. 

Amphasia  Newm. 

In  this  genus,  which  is  again  monotypic,  the  mouth  parts  are 
almost  exactly  as  in  Xestonotus,  'the  ligula  being  very  slender  and 
not  in  the  least  expanded  at  apex  and  the  paraglossae  fully  as  long, 
rather  broad  and  obtuse  at  apex,  but  otherwise,  and  especially  in 
type  of  coloration  and  sculpture,  which  may  become  of  generic 
significance  in  some  groups  of  Carabidae,  there  is  no  similarity 
whatever.  The  type  of  Amphasia  may  be  described  as  follows: 

Form  oblong,  rather  feebly  convex,  shining  throughout  in  both  sexes, 
pale  testaceous  in  color  throughout  the  body,  legs  and  trophi,  except 
that  the  elytra  are  dark  brown  and  the  entire  sterna  and  parapleura 
of  the  hind  body  deep  black;  head  rather  small  and  long,  one-half 
as  wide  as  the  prothorax,  the  neck  somewhat  constricted  behind  the 
moderate  though  very  prominent  eyes,  the  foveae  very  small  but  only 
moderately  deep  and  elongate-oval;  antennae  slender,  rather  pale 
brown,  the  two  basal  joints  paler  and  testaceous;  prothorax  two- 
fifths  (cf1)  to  one-half  (9)  wider  than  long,  the  sides  parallel  and 
evenly,  somewhat  strongly  arcuate;  apex  deeply  sinuate,  with 
advanced  and  only  rather  narrowly  rounded  angles  and  distinctly 
narrower  than  the  base,  which  is  transverse,  rounding  laterally,  the 
angles  very  broadly  rounded,  the  fine  basal  bead  usually  broadly 


HARPALIN.E  195 

interrupted  medially;  surface  with  coarse  sparse  punctures  apically 
and  laterally,  which  become  scarcely  at  all  smaller  and  very  dense 
latero-basally,  the  lateral  gutter  rather  coarse,  disappearing  on  the 
flattened  latero-basal  area  at  about  basal  third,  the  foveae  extremely 
shallow  and  vague;  elytra  not  quite  one-half  longer  than  wide,  just 
visibly  wider  than  the  prothorax,  with  parallel  and  feebly  arcuate 
sides  and  obtusely  rounded  apex,  the  sinus  long  and  feeble  but 
evident,  the  striae  fine  but  somewhat  impressed,  coarser  and  with 
rather  convex  intervals  suturally,  the  intervals  elsewhere  feebly 
convex  and  all  covered  with  rather  dense  confused  punctuation, 
each  puncture  bearing  a  short  fulvous  hair,  the  punctures  coarse 
suturally,  finer  elsewhere,  the  lateral  line  of  foveae  not  at  all  inter- 
rupted; discal  puncture  small,  at  three-fifths;  hind  tarsi  slender, 
sparsely  hairy  above,  the  basal  joint  nearly  as  long  as  the  next  three 
combined,  the  second  not  quite  as  long  as  the  fifth;  abdomen  finely, 
sparsely  punctulate  throughout.  Length  (cf  9 )  8.5-10.0  mm.; 
width  3.0-4.0  mm.  Long  Island  to  Missouri.  Abundant.  [A. 
fulvicollis  Newm.,  Harpalus  obscuripennis  Dej.  and  Feronia  inter- 
stitialis  Say] interstitialis  Say 

This  species  was  also  omitted  in  the  review  of  Dr.  Horn  mentioned 
under  Xestonotus,  but  sericeus  Harr.,  was  included. 

Pseudamphasia  n.  gen. 

While  there  is  some  similarity  between  this  genus,  also  mono- 
typic,  and  the  preceding,  due  to  the  close  punctuation  and  pubes- 
cence, the  structure  of  the  ligula  is  so  different  as  to  indicate  that 
there  is  but  little  real  affinity.  The  ligula  is  rather  slender  basally, 
but  rapidly  and  very  broadly  expands  apically  to  the  broadly 
truncate  apex;  the  paraglossae  are  narrower  than  in  Amphasia  and 
narrowly  rounded  at  tip.  The  terminal  spur  of  the  anterior  tibiae 
is  simple  and  slender  and  the  antennae  of  the  male  extend  nearly  to 
basal  fourth  of  the  elytra.  The  fifth  hind  tarsal  joint  is  relatively 
shorter  than  in  any  other  species  recalled  at  present.  The  type  is 
as  follows: 

Body  oblong-oval,  very  moderately  convex,  rather  shining,  black,  the  ely- 
tra feebly  (c?)  or  densely  (9  )  sericeous;  under  surface  and  femora 
black,  the  tibiae  and  tarji  testaceous;  head  rather  short,  slightly  more 
than  half  as  wide  as  the  prothorax,  with  a  few  punctures  basally 
and  near  the  rather  large  shallow  and  somewhat  vague  foveae,  the 
eyes  unusually  large  and  very  prominent;  antennae  very  slender, 
somewhat  dusky-testaceous  throughout;  prothorax  but  little  more 
than  a  third  wider  than  long,  the  sides  subparallel,  evenly  and  rather 
strongly  arcuate,  the  apex  deeply  sinuate,  with  advanced  and  but 
very  narrowly  rounded  angles  and  much  narrower  than  the  base, 


196  MEMOIRS  ON  THE  COLEOPTERA 

\vhich  is  transverse  medially,  feebly  arcuate  laterally,  the  angles 
broadly  rounded;  surface  strongly  but  rather  sparsely  punctured 
throughout,  the  punctures  becoming  dense  in  the  large  concavo- 
explanate  latero-basal  region,  which  probably  represents  the  foveae 
as  these  are  wholly  undefined;  the  marginal  gutter  is  narrow  ante- 
riorly, gradually  broader  posteriorly,  rather  abruptly  defined  and 
closely  punctate,  disappearing  at  about  basal  two-fifths;  the  stria 
is  extremely  fine  and  broadly  biabbreviated,  the  surface  adjacent 
thereto  somewhat  flattened;  elytra  nearly  one-half  longer  than  wide, 
fully  a  fourth  wider  than  the  prothorax,  the  sides  parallel  and  broadly 
arcuate,  the  apex  obtusely  rounded;  sinu-  rather  short,  feeble  but 
very  distinct;  surface  densely,  rather  finely  and  uniformly  punctate 
and  minutely  pubescent  throughout,  the  striae  fine,  the  scutellar 
long,  the  intervals  nearly  flat  throughout,  3-5-7  with  scattered  sparse 
coarser  punctures  throughout  the  length,  which  are  distinct  (c?)  or 
feebly  defined  (9),  the  discal  substrial  puncture  small,  at  three- 
fifths;  abdomen  very  finely  and  sparsely  punctulate  throughout; 
hind  tarsi  slender,  with  only  very  few  hairs  above,  the  basal  joint 
longer  than  the  next  two  combined  and  about  as  long  as  the  last 
three.  Length  (d71  9  )  8.8-9.8  mm.;  width  3.3-4.0  mm.  Rhode 
Island  to  Lake  Superior  and  Louisiana.  Abundant.  [Harpaliis 
femoratus  Dej.] sericea  Harr. 

The  coarsely  and  sparsely  punctured  alternate  intervals  of  the 
elytra  would  ally  the  genus  with  Anadaptus,  except  that  here  the 
punctured  intervals  are  3-5-7,  and  not  the  alternate  intervals 
beginning  with  the  second  as  in  Anadaptus  porosus;  this  is  a  very 
singular  and  exceptional  feature  in  sericea. 

Dicheirus  Mann. 

We  come  here  upon  a  series  of  generic  types  differing  in  a  note- 
worthy way  from  those  that  precede  in  the  short  basal  joint  of  the 
hind  tarsi,  either  actually,  due  to  the  very  much  shorter  tarsus, 
or  relatively  as  in  D.  piceus  and  allied  species,  where  the  first  joint 
is  very  much  shorter  than  the  next  two  combined ;  in  species  of  the 
dUatatus  type,  the  principal  abbreviation  of  the  tarsus  appears  in 
joints  2-4,  so  that  the  basal  joint  may  still  be  as  long  as  the  next 
two  combined  or  nearly  so,  although  never  longer  and  often  shorter 
than  the  fifth.  The  tarsi  in  this  genus  are  conspicuously  and 
sometimes  rather  closely  pubescent  above,  whereby  in  addition  it 
differs  from  the  genera  that  precede.  The  terminal  spur  of  the 
anterior  tibiae  is  strongly  trifid  throughout.  In  general  habitus  it 
differs  completely  from  Anisodactykis  or  any  close  relative  of  that 
genus,  being  smaller  in  size  of  body,  narrow  in  form  and  constantly

having  two  series  of  setigerous  punctures  on  each  elytral  interval, 
the  series  very  close  to  the  striae  as  a  rule.  The  two  principal  groups 
of  Dicheirus  differ  from  each  other  almost  subgenerically  as  follows: 

Body  usually  but  feebly  convex,  the  prothorax  much  narrowed  basally 
and  cordiform;  ligula  slender,  though  gradually  somewhat  broader 
apically,  the  paraglossse  not  very  broad,  somewhat  produced  ex- 
ternally at  apex,  this  apical  part  generally  curving  inward;  palpi 
stout,  the  last  two  joints  of  the  labial  extremely  unequal,  the  third 
scarcely  three-fifths  as  long  as  the  second,  which  is  unusually 
elongate;  joints  2-4  of  the  hind  tarsi  unusually  abbreviated;  body 

generally  brown  in  color 2 

Body  strongly  and  subcylindrically  convex  as  a  rule,  the  prothorax  never 
more  than  very  feebly  narrowed  posteriorly;  erect  hairs  of  the  upper 
surface  always  very  short;  ligula  and  paraglossae  nearly  as  in  the 
preceding  section,  the  palpi  much  more  slender,  the  third  joint  of 
the  labial  not  very  much  shorter  than  the  second;  joints  2-4  of  the 
hind  tarsi  not  so  abbreviated;  basal  joint  of  the  antennae  not  quite 

so  thick;  body  generally  deep  black  in  color 8

narrower  than  the  broadly  sinuate  apex;  surface  almost  even,  slightly 
depressed  latero-basally  but  not  otherwise  modified,  the  foveae

decoloratus  n.  sp. 

The  two  principal  groups  in  this  genus  are  very  clearly  defined 
and  have  somewhat  the  nature  of  subgenera.  The  species  are 
much  more  closely  allied  among  themselves  in  the  piceus  than  in 
the  more  diversified  dilatatus  section.  There  are  undoubtedly  a 
considerable  number  of  forms  closely  allied  to  piceus,  and  I  have 
ventured  to  define  a  number  of  them  above,  but  have  been  unable 
to  identify  any  of  them  with  villosus  or  irregularis  of  Motschulsky, 
the  above  synonymy  being  that  of  Horn;  parallelus  of  LeConte  is 
however  typical  piceus.  D.  pallidus  Mots.,  is  Agonoderus  rugicollis 


02  MEMOIRS  ON  THE  COLEOPTERA 

Lee.,  of  the  Acupalpini.  The  following  species  cannot  be  placed 
properly  in  the  table  given  above;  the  table  is  based  upon  that 
of  Dr.  Horn,  for  the  reason  that  so  many  of  the  species  are  unknown 
to  me  in  nature: 

D.  immanis  Horn.  (Anisodactylus) — Oblong,  depressed,  piceous, 
feebly  shining  and  pubescent,  the  legs  rufous;  head  coarsely  but  not  deeply 
punctate,  with  ~>hort  erect  hairs,  the  epistoma  with  one  setigerous  puncture 
at  each  angle;  prothorax  broader  than  long,  narrowed  posteriorly,  the 
sides  in  front  arcuate,  posteriorly  oblique,  the  hind  angles  distinct  but 
not  prominent;  base  on  each  side  slightly  arcuate;  surface  feebly  convex, 
coarsely  but  not  deeply  punctate  and  with  very  short  erect  hiirs;  elytra 
wider  than  the  prothorax,  oblong-oval,  the  sides  slightly  arcuate;  striae 
fine,  the  intervals  flat,  rather  finely  and  closely,  biseriately  punctulate  and 
with  very  short  erect  hairs;  prothorax  beneath  with  a  few  coarse  punc- 
tures in  front;  abdomen  and  sides  of  metasternum  sparsely  punctulate; 
hind  tibia?  with  short  broad  spatuliform  spurs.  Length  8.5  mm.  Cali- 
fornia (San  Joaquin  Valley). 

The  author  states  that  he  is  disposed  to  regard  the  peculiar  forma- 
tion of  the  hind  tibial  spurs  as  specific,  because  he  had  before  him 
two  perfectly  similar  specimens,  both  females.  The  characters 
given  fit  those  of  brevisetosus  very  well,  that  species  being  founded 
upon  a  single  male,  which  however  has  perfectly  normal  and  slender, 
finely  pointed  hind  tibial  spurs;  as  there  is  no  trace  of  dense  hairs 
on  the  under  surface  of  the  middle  tarsi,  it  cannot  be  obtusus  Lee. 
It  would  be  interesting  to  observe  the  male  of  immanis. 

The  following  species  is  also  unknown,  beyond  the  unique  type 
in  the  Dejean  collection;  the  description  is  curtailed  from  that  of 
Dejean : 

D.  brunneus  Dej.  (Harpalus] — Oblong-ovate,  subparallel,  sub- 
pubescent,  nigro-piceous,  the  antennae  and  legs  rufous;  head  and  prothorax 
deeply  punctate,  the  prothorax  subquadrate,  slightly  narrowed  posteriorly, 
the  hind  angles  right;  elytra  striate,  the  intervals  with  two  lines  of  im- 
pressed punctures;  hairs  of  the  upper  surface  sparse  and  moderately  long; 
punctures  of  the  head  coarse  and  very  dense;  the  prothorax  is  only  a 
little  wider  than  long,  feebly  rounded  at  the  sides,  feebly  narrowed 
posteriorly  and  rather  convex,  having  coarse  deep  punctures,  which  are 
very  dense  and  often  coalescent;  the  punctures  of  the  binary  elytral 
series  are  moderately  close-set;  there  is  but  a  single  series  on  the  sutural 
interval  and  the  ninth  has  numerous  punctures  placed  without  order. 
Length  (9)6  mm.;  width  2  mm.  California.  Sent  to  Count  Dejean 
by  Eschscholtz. 

This  is  evidently  different  from  any  species  known  to  me,  but 
may  be  placed  just  after  decoloratus  at  the  end  of  the  table;  it 


HARPALIN.E  203 

differs  profoundly  from  that  species  in  the  very  small  size,  slender 
form  and  dense  or  coalescent  punctures  of  the  pronotum.  That 
it  belongs  to  the  piceus,  rather  than  the  dilatatus,  section  of  the 
genus,  I  think  is  sufficiently  evident  because  of  the  laterally  feebly 
rounded  and  but  slightly  basally  narrowed  prothorax.  It  certainly 
cannot  be  allied  in  any  way  closely  with  angulatus,  where  the 
thoracic  punctures  are  sparse  and  the  size  much  larger.  It  is  a 
very  interesting  species  that  it  is  hoped  may  be  rediscovered  in  the 
course  of  time. 

Anadaptus  n.  gen. 

The  body  here  is  more  or  less  narrowly  elongate-suboval,  strongly 
convex,  with  cordiform  prothorax,  having  the  basal  angles  sharply 
marked  as  a  rule  and  the  elytral  striae  deeply  impressed,  except  in 
some  of  the  Pacific  species,  where  the  striae  are  feebler  and  the 
strial  intervals  more  or  less  punctate,  never  serially  however  as  in 
Dicheirus  but  confusedly  over  their  entire  breadth.  The  ligula  is 
moderately  wide,  gradually  and  only  slightly  broadening  to  the 
apex,  the  paraglossae  with  the  outer  part  of  the  apex  prolonged  and 
sometimes  curling  inward.  The  species  have  a  peculiar  habitus 
which  indicates  at  a  glance  that  they  constitute  a  genus  different 
from  Anisodactyhis,  where  they  have  been  assigned  hitherto;  I 
have  but  little  doubt  that  the  genus  is  desirable  in  the  present  state 
of  taxonomy  and  therefore  valid.  The  species  are  moderately 
numerous,  those  known  thus  far  being  the  following: 

Elytral  intervals  not  alternately  punctate;  body  partially  pale  in  color, 

never  metallic  in  lustre 2 

Elytral  intervals  alternately  punctured  throughout  their  width;  body 
entirely  dark  in  color,  with  more  or  less  obvious  metallic  lustre.  .  .5

head  rather  short,  fully  two-thirds  as  wide  as  the  prothorax,  with 
prominent  eyes,  outwardly  arcuate  lineiform  foveae  and  rather  short 
blackish,  though  basally  pale,  antennae;  surface  smooth,  punctured 
at  the  sides  basally;  prothorax  a  third  wider  than  long,  the  sides 
broadly  rounded,  moderately  converging  and  just  visibly  sinuate 
basally;  apex  broadly  sinuate,  equal  to  the  base,  which  is  transverse, 
becoming  arcuate  between  the  end  of  the  foveae  and  the  angles,  which 
are  somewhat  obtuse  but  sharply  marked  and  as  a  rule  minutely

distinct;  abdomen  with  some  scattered  fine  punctulation  toward 
base  of  each  segment  except  the  last;  basal  joint  of  the  hind  tarsi 
much  shorter  than  the  fifth.  Length  (9  )  9.2-10.2  mm.;  width  3.7-

As  may  be  noted,  the  species  are  arranged  in  accordance  with 
primary  characters  selected  by  Dr.  Horn  in  the  paper  previously 
mentioned.  I  have  identified  nivalis  from  description  and  do  not 
have  the  male,  but  my  material  in  all  probability  represents  that 
species  correctly,  although  there  is  reason  to  believe  that  the  author 
included  more  than  one  in  his  diagnosis;  the  above  outline  of 
pitychrous  Lee.,  is  also  drawn  from  that  given  by  Horn. 

This  is  one  of  the  most  interesting  genera  of  the  Anisodactylini 
and  the  outward  suggestion  of  Daptns  may  not  be  so  very  fanciful 
after  all,  for  the  hind  tarsi  in  discoideus  are  remarkably  thick  at 
base  and  taper  gradually,  very  much  as  they  do  in  Geopinus — this 
being  another  instance  of  the  parallelisms  that  constantly  recur 
throughout  the  Harpalinae; — the  tapering  hind  tarsi  recall  Geopinus 
at  one  end  and  Agonoderus  near  the  other  end  of  the  series,  as  here 
arranged;  in  every  other  genus  throughout  the  subfamily  the  hind 
tarsi  are  filiform. 

Stilbolidus  n.  gen. 

The  species  of  this  genus  have  given  rise  to  some  divergence  of 
opinion,  Bates  assigning  the  type  to  Anisotarsus,  while  Horn  main- 


HARPALIN^E  207 

tained  that  it  would  be  better  placed  in  Anisodactylus .  The 
former  author  came  the  closer  to  the  real  affinities  involved  but,  as 
there  are  wide  departures  from  both  Anisotarsus  and  Anisodactylus, 
the  best  solution  seems  to  be  the  erection  of  a  distinct  genus  for 
the  Harpalus  mexicanus  of  Dejean  and  one  or  two  allied  species. 
The  mentum  is  definitely  and  distinctly  toothed  as  in  Anisotarsus, 
the  ligula  long,  slender,  gradually  but  very  feebly  enlarged  apically 
and  not  quite  so  long  as  the  larger  and  very  broad,  apically  very 
broadly  obtuse,  paraglossse.  The  labial  palpi  are  thick,  with  the 
third  joint  barely  at  all  shorter  than  the  second  and  rather  rapidly, 
obtusely  acuminate  at  tip.  The  terminal  spur  of  the  anterior  tibiae 
is  very  slender  and  perfectly  simple,  and  the  hind  tarsi  are  rather 
short,  pubescent  above,  with  the  basal  joint  shorter  than  the  next 
two,  though  distinctly  longer  than  the  fifth,  which  is  unusually 
short.  It  will  be  noticed  that  this  formation  of  the  anterior  spur 
and  hind  tarsi  is  very  different  from  the  corresponding  characters 
in  Anisodactylus,  which,  in  conjunction  with  the  broad  obtuse 
paraglossae  and  the  mentum  tooth,  shows  that  the  species  cannot 
properly  be  placed  in  that  genus,  although  more  closely  resembling 
it  to  external  view  and  in  its  compact  robust  form,  than  it  does 
any  other  genus  of  the  tribe.  Stilbolidus  is  very  distinct  also  in 
having  no  trace  of  the  usual  discal  puncture  of  the  elytra,  the 
presence  of  this  puncture  being  an  exceedingly  constant  character 
in  the  Anisodactylini,  as  stated  under  Anisodactylus,  and  its  absence 
in  lodingi  Schf.,  is  an  extraordinary  exception  to  the  general  rule. 
There  seem  to  be  three  species  at  hand  as  follows: 

Body  much  stouter  in  build  and  larger  in  size,  the  elytral  intervals  feebly 
convex  in  both  sexes,  polished  (cf)  or  strongly  alutaceous  (9). 
Color  deep  black  throughout,  the  tarsi  piceous,  the  antennae  blackish 
throughout;  lustre  (cT)  very  highly  polished  and  distinctly  violaceous 
throughout  above,  or  ( 9  )  similar  but  scarcely  at  all  violaceous  and 
with  the  duller  elytra  deep  black;  head  three-fifths  as  wide  as  the 
prothorax,  with  well  developed  prominent  eyes  and  rather  large, 
very  deep  fovese,  the  surface  impunctate,  very  smooth  throughout 
(cf)  or  rugose  anteriorly  (9  );  prothorax  transverse,  more  than  one- 
half  wider  than  long,  the  sides  moderately  rounded,  feebly  converging 
and  becoming  just  visibly  sinuate  basally,  the  angles  slightly  obtuse 
but  very  sharply  marked  and  minutely  subprominent;  base  trans- 
verse, slightly  wider  than  the  very  feebly  sinuate  apex;  surface  very 
smooth  and  without  any  sort  of  sculpture  throughout,  finely  reflexed 
but  with  a  rather  thick  bead  at  the  sides,  the  stria  very  fine  and

with  two  or  three  punctures  as  in  Triplectrus;  abdomen  with  fine 
sparse  punctulation  behind  the  coxae;  hind  tarsi  with  the  first  three

The  species  are  very  much  alike  in  general  features  throughout, 
but  closer  observation  reveals  a  number  of  structural  differences 
relating  to  size,  form,  tarsal  structure  and  modifications  of  the 
elytral  sinus.  It  is  probable  that  Anisotarsns  lamprotus  Bates, 
also  belongs  to  this  genus. 


HARPALIKLE  209 

Anisotarsus  Chd. 

Eurytrichus  Lee. 

This  is  one  of  the  most  distinctly  isolated  genera  of  the  tribe, 
not  only  in  habitus,  due  to  the  elongate-oval  outline,  Calathus-\ike 
form  and  thinness  of  the  integuments,  but  in  the  structure  of  the 
mouth-parts.  The  mentum  is  distinctly  and  angularly  toothed, 
the  ligula  slender,  scarcely  enlarged  at  apex  and  usually  very  much 
shorter  than  the  paraglossae,  the  lobes  of  the  latter  long  and  evenly 
but  not  broadly  rounded  at  tip.  The  second  and  third  joints  of  the 
labial  palpi  are  subequal  in  length.  The  terminal  spur  of  the 
anterior  tibiae  is  slender  and  simple  and  the  hind  tarsi  are  slender, 
subglabrous  above,  with  the  basal  joint  about  as  long  as  the  next 
two  combined  and  longer  than  the  fifth  as  a  rule.  The  sterna  and 
abdomen  are  almost  completely  impunctate.  There  is  constantly  a 
single  discal  elytral  puncture,  which  is  more  posterior  in  position 
than  usual,  but  there  is  no  other  distinct  punctuation,  excepting  the 
uninterrupted  marginal  line  of  large  and  small  fovese.  The  species 
are  decidedly  numerous,  those  known  at  present  from  our  fauna 
being  as  follows: 

Body  notably  large  in  size.  Color  deep  black  throughout,  without  trace 
of  metallic  reflection,  the  tarsi  piceous  or  paler;  lateral  edge  of  the 
pronotum  slightly  pale  diaphanously ;  lustre  shining,  the  elytra  just 
visibly  (cf)  or  strongly  (9)  alutaceous;  head  three-fifths  as  wide 
as  the  prothorax,  with  rather  large  and  prominent  eyes,  smooth,  the 
foveae  minute  and  sublinear;  palpi  slender;  antennae  slender,  tes- 
taceous, the  three  basal  joints  partially  blackish;  prothorax  two- 
fifths  wider  than  long,  the  sides  broadly  and  almost  evenly  rounded, 
a  little  less  arcuate  basally;  apex  moderately  sinuate,  much  narrower 
than  the  base,  which  is  transverse  medially,  broadly  and  feebly 
arcuate  laterally,  the  angles  obtuse,  well  defined  and  only  finely 
blunt  at  their  apices;  surface  subeven,  impunctate  throughout,  the 
lateral  gutter  rather  coarse,  disappearing  near  basal  third,  the  foveae 
very  shallow  and  somewhat  vague,  opaculate  or  rugulose  but  not 
punctate,  the  stria  short,  fine;  elytra  rather  more  than  one-half 
longer  than  wide,  fully  a  fourth  wider  than  the  prothorax,  parallel, 
with  rounded  sides  and,  as  usual,  basally  unexposed  humeri,  the 
apex  gradually  obtusely  ogival,  the  sinus  shallow  but  evident;  striae 
very  fine,  the  scutellar  long;  intervals  perfectly  flat,  the  discal 
puncture  behind  apical  fourth.  Length  (cf  9 )  11.0-12.7  mm.; 
width  4.3-5.0  mm.  Texas  (El  Paso)  and  Arizona.  Abundant  also 
throughout  northern  Mexico.  The  generic  type  of  Anisotarsus.

Testaceus  Hald.,  seems  to  be  specifically  different  from  terminates 
and  I  have  therefore  reinstated  it;  the  very  pale  coloration  is  appar- 
ently constant  and  is  not  accompanied  by  the  desiccatory  distortion 
usual  in  cases  of  immaturity,  although  the  integuments  are  very 
thin  even  for  the  present  genus.  There  are  several  species  that 
I  am  unable  to  recognize  among  my  material ;  these  are  as  follows, 
with  characters  drawn  from  available  descriptions: 

A.   maculicornis    Chd.    (Harpalus). — Oblong,    black,    shining;    pro- 
thorax  one-half  wider  than  long,  slightly  narrowed  anteriorly,  the  sides 


216  MEMOIRS  ON  THE  COLEOPTERA 

moderately  rounded,  broadly  subdepressed  posteriorly,  the  hind  angles 
obtuse;  base  feebly  impressed  at  each  side;  elytra  striate,  the  intervals 
barely  convex,  the  third  unipunctate  posteriorly;  antennae  and  palpi 
rufous,  the  former  with  joints  2-6  more  or  less  nigrescent.  Length  14.5 
mm.  Louisiana. 

The  characters  are  taken  from  LeConte's  description  (Tr.  Am. 
Phil.  Soc.,  1853,  p.  384);  the  only  one  mentioned  which  is  of  any 
great  comparative  value  is  the  size  of  the  body,  and  this  indicates 
that  the  species  should  be  placed  next  to  brevicollis  Chd.,  in  the 
above  table. 

A.  nitidipennis  Lee. — Oblong,  rather  narrower  than  agilis,  shining, 
obscure  viridi-aeneous,  the  head  and  prothorax  more  obscure;  head  two- 
thirds  as  wide  as  the  prothorax,  smooth,  the  frontal  impressions  puncti- 
form;  antennae  with  the  three  basal  joints  rufo-testaceous,  the  remainder 
maculate  with  brown;  prothorax  somewhat  narrowed  behind,  fully 
one-half  wider  than  long,  quadrate,  truncate  at  apex  and  base,  the  sides 
rounded;  hind  angles  obtuse,  not  rounded,  scarcely  explanate;  surface 
somewhat  convex,  the  margin  depressed;  anterior  transverse  impression 
deep,  angulate,  the  stria  fine,  biabbreviated,  the  foveee  linear;  elytra 
parallel,  the  apices  only  slightly  sinuate,  striate,  the  intervals  accurately 
flat,  the  third  unipunctate,  the  marginal  series  of  foveae  interrupted 
medially;  under  surface  black,  the  legs  and  trochanters  rufous.  Length 
7.5  mm.;  width  2.8  mm.  Georgia.  A  single  specimen. 

There  can  be  but  little  doubt  that  this  species  belongs  near 
cephalus  and  tenuitarsis ,  which  together  form  a  very  isolated 
section  of  the  genus,  but  in  neither  of  them  could  the  anterior 
margin  of  the  prothorax  be  described  as  truncate;  the  sinus  is 
distinct  and  well  developed,  though  only  moderately  deep.  The 
coloration  of  the  antennae,  also,  seems  to  be  different;  the  joints 
beyond  the  third  in  cephalus  and  tenuitarsis,  have  a  faint  blackish 
slender  line  along  the  middle  of  the  flattened  sides,  as  is  often  the 
case  in  other  unrelated  forms,  but  this  would  hardly  suit  the 
language  of  the  description.  LeConte  states  that  nitidipennis  is 
related  to  agilis,  which  is  clearly  not  the  case  with  the  two  species 
mentioned. 

A.  flebilis  Lee.  (Eurytrichus). — Oblong,  piceous-black,  somewhat 
shining;  prothorax  more  than  one-half  wider  than  long,  equally  narrowed 
anteriorly  and  posteriorly,  the  sides  rounded,  oblique  posteriorly,  the 
hind  angles  obtuse,  not  at  all  rounded;  surface  feebly  impressed  at  each 
side  of  the  base;  elytra  slightly  wider  than  the  prothorax,  finely  striate, 
the  second  stria  unipunctate  posteriorly;  antennae,  palpi  and  legs  piceo- 
rufous.  Length  8.8-10  mm.  Lower  California  (Cape  San  Lucas). 
Quite  distinct  from  our  other  species  by  the  form  of  the  prothorax;  the 
sides  behind  are  scarcely  perceptibly  flattened. 


HARPALIN^E  217 

Probably  related  to  calathoides,  but  the  thoracic  apex  is  much 
narrower  than  the  base  in  that  species  and  not  subequal  in  width 
as  might  be  inferred  from  the  description  of  flebilis;  this,  when 
considered  in  connection  with  the  facts  that  the  tip  of  Lower  Cali- 
fornia is  in  a  somewhat  different  zoological  region  from  Arizona  and 
the  rest  of  the  California  Peninsula  and  that  the  species  are  some- 
what numerous  in  the  Sonoran  regions,  renders  actual  specific 
identity  in  this  case  highly  improbable. 

Spongopus  Lee. 

This  genus  is  also  one  of  the  more  distinctly  characterized 
members  of  the  Anisodactylini,  having  a  facies  entirely  its  own, 
due  to  the  short  cordiform  prothorax  and  large  and  very  elongate 
elytra,  when  compared  with  the  anterior  parts.  It  is  allied  closely 
to  Anisotarsus,  but  differs  in  the  dense  hard  integuments  among 
other  features.  The  mentum  tooth  is  only  moderate  in  size  as  in 
Anisotarsus,  but  is  triangular,  clearly  denned  and  constant.  The 
ligula  is  rather  slender  and  is  gradually  and  only  very  slightly 
broader  apically;  the  paraglossae  are  an  extreme  development  of 
forms  frequently  observed  in  the  tribe,  the  outer  part  of  the  apex 
being  greatly  prolonged  into  a  slender  process,  extending  far  beyond 
the  tip  of  the  ligula  and  with  its  apex  somewhat  curving  inward. 
The  labial  palpi  are  long  and  slender,  the  third  joint  but  little 
shorter  than  the  second,  which  has  many  long  bristling  setae  along 
its  anterior  side  as  usual  in  the  tribe.  The  terminal  spur  of  the 
anterior  tibiae  is  long  and  very  slender,  but  nevertheless  has  the 
posterior  side  arcuate  basally,  while  the  anterior  side  is  almost 
perfectly  straight.  The  hind  tarsi  are  long,  with  some  irregular 
punctures  and  short  hairs  dorsally,  the  first  joint  about  as  long  as 
the  next  two  and  equal  to  the  fifth,  the  claws  strongly  arcuate  and 
well  developed.  The  elytra  have  a  fine  suffused  punctulation,  but 
the  abdomen  is  smooth,  excepting  the  usual  fine  post-coxal  punc- 
tures. The  type  species  may  be  known  by  the  following  characters: 

Body  above  and  beneath  rather  deep  black,  strongly  shining  throughout 
above  in  both  sexes,  there  being  absolutely  no  apparent  sexual 
difference  of  any  kind;  legs  and  antennae  rufo-testaceous;  head 
evidently  more  than  half  as  wide  as  the  prothorax,  almost  smooth, 
with  very  prominent  eyes  and  unusually  large  deep  irregular  foveae, 
which  have  a  ramus  curving  outwardly,  generally  almost  to  the  eyes; 
antennae  long,  rather  slender;  transverse  red  spot  of  the  vertex

conspicuous;'  prothorax  fully  one1half  wider  than  long,  strongly 
rounded  at  the  sides  anteriorly,  the  sides  gradually  oblique  and 
straight  posteriorly  to  the  obtuse  angles,  which  are  sharply  denned  and 
often  minutely  prominent;  apex  broadly  and  moderately  sinuate  and 
subequal  to  the  very  feebly  arcuate  base,  which  is  finely  and  strongly, 
evenly  beaded;  surface  moderately  convex,  smooth,  with  vestiges 
of  minute  sparse  punctulation  throughout,  rather  broadly  reflexed 
and  rugosely  punctate  at  the  sides,  the  gutter  even  in  width  from 
apex  to  basal  third  where  it  disappears  in  the  large  concavo-ex- 
planate  latero-basal  parts,  which  merge  gradually  into  the  large  and 
rather  deep,  rounded  and  coarsely,  densely  punctured  fovese;  the 
median  parts  of  the  base  are  also  depressed  and  distinctly  punctured; 
anterior  impression  distinct,  rather  closer  to  the  apex  than  in 
Anisotarsus;  stria  distinct  and  subentire;  elytra  oblong,  parallel, 
with  feebly  arcuate  sides,  rather  more  than  one-half  longer  than  wide 
and  a  third  wider  than  the  prothorax,  obtuse  at  apex,  the  sinus  long 
and  distinct;  striae  strong  and  impressed,  the  scutellar  very  long; 
intervals  rather  strongly  convex  throughout,  the  discal  puncture 
coarse  and  at  three-fifths;  suffused  punctures  dense  near  the  sides, 
where  they  bear  minute  hairs.  Length  (cf1  9  )  12.8-13.5  mm.; 
width  4.8-5.0  mm.  North  Carolina  (Asheville),  Iowa  and  Kansas. 

verticalis  Lee. 

The  genus  Spongopus  was  considered  as  scarcely  distinct  from 
Anisotarsus  by  Lacordaire,  but  it  has  an  altogether  different 
habitus,  as  may  be  inferred  from  the  description,  and  is  without 
much  doubt  a  distinct  genus. 

The  Central  American  Notiobia  leiroides  and  parilis  of  Bates, 
of  which  I  have  specimens  from  Honduras,  almost  exactly  resemble 
Spongopus  verticalis  in  outline,  facies  and  in  the  dense  integuments, 
but  the  eyes  are  larger  and  more  conspicuous;  the  transverse  cordi- 
form  prothorax  is  similar  in  the  sharply  marked  hind  angles,  but 
is  without  lateral  or  basal  punctuation;  the  elytra  are  devoid  of 
all  trace  of  diffused  punctuation  and  the  paraglossse  are  entirely 
different  in  form,  being  broadly  truncate  at  apex  and  not  in  the 
least  prolonged  at  the  external  apical  angle.  The  mentum  tooth 
is  well  developed,  much  as  in  Spongopus.  In  a  natural  arrangement 
Notiobia  Perty,  would  therefore  come  between  Anisotarsus  and 
Spongopus.  The  elytral  striae  in  parilis  are  sulciform  and  are 
especially  deep  along  the  summit  of  the  lateral  declivity. 

Tribe  ACUPALPINI. 

The  chief  distinguishing  characters  of  this  tribe  are  the  bisetose 
second  labio-palpal  joint  and  the  form  of  the  frontal  fovese;  it 


HARPALIN.E  219 

should  be  added  also  that  the  body  is  always  small  or  very  small 
in  size.  The  genera  are  numerous,  perhaps  more  so  when  compared 
with  the  known  species  than  in  most  of  the  other  tribes,  indicating 
an  unusual  amount  of  structural  diversification ;  for  example,  nearly 
all  the  male  tarsal  modifications  of  all  the  preceding  tribes  occur 
here,  from  the  solidly  pubescent  A nisodactylus-\ike  soles  of  Pel- 
matelhis,  through  the  biserially  squamulose  Harpalns-Yike  develop- 
ments seen  in  the  Bradycellids  and  in  Stenolophus,  to  the  sexually 
unmodified  tarsi  of  Agonoderus,  representing  the  Daptid  type,  and, 
as  in  Geopinus  of  the  Daptini,  the  hind  tarsi  in  Agonoderus  are  of  a 
somewhat  tapering  form.  There  is  comparatively  little  variety, 
so  far  as  observed,  in  the  ligula  and  paraglossse,  but  the  presence  or 
absence  of  a  mentum  tooth  is  taxonomically  much  more  important 
here  than  in  the  Harpalini  and  even  somewhat  more  so  than  in  the 
Anisodactylini.  The  last  joint  of  all  the  palpi  is  frequently  more 
subulate  at  apex  than  in  the  preceding  tribes  and  the  third  joint  of 
the  labial  palpi  is  nearly  always  much  longer  than  the  second. 
The  essential  differential  characters  distinguishing  the  genera 
represented  in  the  material  at  hand  may  be  expressed  briefly  as 
follows : 

Mentum  toothed,  the  anterior,  at  least,  of  the  male  tarsi  moderately 
dilated  and  squamulose  beneath;  hind  tarsi  always  slender  and  fili- 
form   2 

Mentum  not  toothed;  antennae  with  but  two  glabrous  basal  joints,  as 
usual  in  the  subfamily 13

3 — Palpi  long  and  slender,  the  second  joint  of  the  labial  as  long  as  the 
third  and  with  about  three  long  setae;  anterior  tarsi  (cf)  broadly 
dilated,  the  joints  2-4  transverse,  clothed  beneath  with  a  loose  but 
rather  uniform  mixture  of  long  hairs  and  hair-like  squamae,  the 
middle  tarsi  slender,  barely  at  all  dilated  and  with  a  few  squamae; 
upper  surface  with  uniform  strong  micro-pubiferous  punctulation 
throughout,  the  third  and  fifth  strial  intervals  with  widely  spaced 
series  of  slightly  coarser  punctures.  Palaearctic  regions. 

*Dicheirotrichus 

Palpi  all  short  and  relatively  stout,  the  second  joint  of  the  labial  bisetose, 
as  usual  in  the  tribe,  and  a  little  shorter  than  the  third;  anterior 
tarsi  (cf)  feebly  dilated,  rather  flattened,  the  joints  subquadrate, 
clothed  uniformly  and  closely  beneath  joints  1-4  with  slender  sub- 
decumbent  squamules,  which  extend  transversely  from  the  median 
line,  the  middle  tarsi  slender  and  unmodified;  upper  surface  with

Remarks  on  the  exotic  genera  introduced  above  may  be  made  as 
follows : 

DICHEIROTRICHUS  Duval. — This  is  one  of  the  most  remarkably 
isolated,  yet  synthetic  genera  of  the  entire  subfamily  and  consists 
of  five  or  six  species,  confined  to  the  European  faunal  regions. 
It  is  somewhat  intermediary  between  the  divisions  of  the  subfamily 
based  upon  the  structure  of  the  labial  palpi,  and  the  male  tarsal 
soles  are  clothed  in  a  peculiar  manner,  not  exactly  as  in  Aniso- 
dactylini  and  widely  different  from  the  form  developed  in  Tricho- 
cellus  and  Stenolophus.  In  general  appearance  the  genus  undoubt- 
edly harmonizes  better  with  Trichocellus,  and  hence  with  the  other 
Acupalpids,  than  it  does  with  any  of  the  Anisodactylini.  On  ac- 
count of  the  possession,  in  common  .with  Diachromus  and  TricJio- 
celhis,  of  a  long  erect  seta  at  the  hind  angles  of  the  prothorax,  a 
character  unknown  elsewhere  in  the  subfamily,  it  might  perhaps 
be  more  logical  to  assign  these  three  genera  to  a  special  tribe. 

BRADYCIDUS  n.  gen. — This  genus  is  rather  closely  allied  to 
Bradycellus,  but  differs  in  many  features  structural  as  well  as 
habital;  the  body  is  more  oblong  and  less  ventricose,  the  emargi- 
nation  of  the  mentum  deeper  and  the  tooth  small  and  broadly 
rounded,  this  being  a  modification  in  the  direction  of  Stenolophus, 
and  the  anterior  and  middle  tarsi  of  the  male  are  almost  exactly 
as  in  that  genus  and  Episcopellus,  both  being  moderately  dilated 
and  with  two  series  of  elongate  scale-like  plates  beneath.  The 
palpi  are  slender,  the  third  joint  of  the  labial  very  gradually  and 
gently  narrowed  from  near  the  base  to  the  apex,  narrowly  truncate, 
the  fourth  joint  of  the  maxillary  not  quite  twice  as  long  as  the 
third.  The  frontal  foveae  are  minute,  punctiform  and  not  at  all 
obliquely  prolonged,  this  formation  being  an  exception  in  the 


HARPALIN.E  223 

Acupalpini  and  of  a  common  Harpalid  type;  the  third  antennal 
joint  is  nearly  like  the  fourth  in  form,  color  and  vestiture;  the  hind 
tarsi  are  long  and  slender  and  the  prosternal  process  has  at  tip  two 
strong  setae.  The  single  species  is  the  following: 

*B.  veneris  n.  sp. — Oblong-suboval,  rather  convex,  shining,  deep 
black,  the  elytra  with  feeble  greenish  lustre,  the  suture  and  thoracic  edges 
feebly  pallescent;  under  surface  black,  the  legs  rather  pale  piceous;  palpi 
blackish-piceous,  pale  at  apex;  head  moderate,  three-fifths  as  wide  as  the 
prothorax,  rather  constricted  behind  the  moderate  but  rather  prominent 
eyes;  antennae  very  slender  and  filiform,  longer  than  the  head  and  pro- 
thorax,  dusky,  the  two  basal  joints  paler;  prothorax  not  quite  one-half 
wider  than  long,  widest  very  slightly  before  the  middle,  the  sides  broadly, 
subevenly  rounded,  nearly  straight  basally;  apex  sinuato-truncate,  with 
narrowly  rounded  angles,  narrower  than  the  base,  which  is  transverse, 
straight  and  minutely  beaded,  the  angles  slightly  more  than  right  and 
only  very  finely  blunt  at  their  tips;  surface  smooth  and  subeven,  with 
fine  subentire  stria  and  fine  even  reflexed  sides,  the  fovese  sublinear  though 
feeble,  somewhat  opaculate  or  subrugulose  but  not  evidently  punctate; 
elytra  nearly  one-half  longer  than  wide  and  a  fourth  wider  than  the  pro- 
thorax,  parallel,  with  broadly  arcuate  sides  and  rounded  apex,  the  sinus 
wide  and  feeble  though  evident;  striae  fine  but  rather  deep,  the  scutellar 
moderately  long,  subparallel,  with  the  fovea  strong;  intervals  flat  or  very 
nearly,  the  discal  puncture  behind  apical  third;  lateral  line  of  foveaa 
clearly  interrupted  medially;  abdomen  smooth;  hind  tarsi  very  slender, 
but  slightly  shorter  than  the  tibiae,  the  first  three  joints  uniformly  and 
gradually  decreasing  in  length,  the  first  fully  as  long  as  the  fifth,  the  claws 
very  slender  and  delicate.  Length  (cf )  5.0  mm. ;  width  2.0  mm.  Cape  of 
Good  Hope  (Wellington). 

Were  it  not  for  the  bisetose  second  labio-palpal  joint,  this  species 
could  very  well  be  regarded  as  a  minute  Harpalus.  The  single 
example  was  taken  by  the  writer  while  a  member  of  the  Transit  of 
Venus  expedition  of  1882,  under  Prof.  Simon  Newcomb. 

BRADYCELLUS  Erichs. — The  species  assumed  as  typifying  this 
genus  in  the  above  table  is  the  collaris  of  Paykull.  The  body  is 
more  ventricose  than  in  any  of  the  American  allied  forms,  but 
the  first  three  antennal  joints  are  similarly  glabrous;  the  mentum 
tooth  is  well  developed,  triangular  and  very  acute  at  tip,  the 
mental  emargination  very  shallow;  the  second  labio-palpal  joint  is 
elongate-oval,  not  compressed  and  much  shorter  than  the  third, 
which  rapidly  becomes  finely  subulate  at  tip;  the  last  joint  of  the 
outer  maxillary  lobe  has  a  peculiarly  inflated,  apically  subulate 
form,  somewhat  like  that  of  the  third  labio-palpal  joint  but  more 
slender;  the  last  joint  of  the  maxillary  palpi  is  twice  as  long  as  the 


224  MEMOIRS  ON  THE  COLEOPTERA 

preceding  joint  and  is  much  more  gradually  pointed  than  that  of 
the  labial  palpi.  The  single  discal  puncture  of  the  elytra  is  ex- 
tremely minute,  the  lateral  line  of  foveae  broadly  interrupted 
medially,  the  striae  deep  and  abrupt  and  the  scutellar  stria  short 
but  distinct,  extending  from  an  unusually  strong  deep  annulate 
fovea.  The  antennae  and  hind  tarsi  are  distinctly  short  when 
compared  with  most  of  the  American  types,  and  I  have  at  present 
scarcely  any  doubt  of  the  generic  distinctness  of  all  the  latter  as 
denned  in  the  table. 

GONIOCELLUS  n.  gen.- — The  body  here  is  somewhat  ventricose 
as  in  Bradycelhis,  but  the  hind  body  is  oblong  and  parallel  and 
not  so  oblong-oval  and  with  rather  strongly  arcuate  sides  as  it  is 
in  that  genus,  and  the  prothorax  is  of  an  entirely  different  shape, 
being  sinuously  narrowed  basally,  with  right  and  very  sharply 
defined  basal  angles.  The  mental  emargination  is  similarly  very 
shallow  and  the  tooth  large  and  very  acutely  triangular.  The 
palpi  and  maxillary  lobe  are  also  nearly  as  in  Bradycellus,  except 
that  the  last  joint  of  the  palpi  is  very  much  more  gradually  pointed 
and  the  outer  lobe  of  the  maxilla  less  inflated  basally,  longer  and 
much  more  gradually  drawn  out  into  a  fine  point  apically.  The 
antennae  are  more  slender  and  have  but  two  glabrous  joints,  the 
third  being  nearly  like  the  fourth,  though  notably  more  elongate. 
The  elytral  striae  are  deeply  impressed,  sulciform,  the  scutellar 
wholly  wanting,  although  the  fovea  is  well  developed;  the  discal 
puncture  is  strong  and  the  lateral  line  of  foveae  very  widely  inter- 
rupted. The  hind  tarsi  are  very  slender  and  more  or  less  notably 
long.  There  are  two  species  before  me,  which  may  be  described 
as  follows,  bifossifrons  being  the  type : 

*G.  bifossifrons  n.  sp. — Convex,  strongly  shining,  blackish-piceous, 
the  thoracic  margins  somewhat  paler,  the  head  also  not  so  dark  as  the 
elytra;  legs  honey-yellow;  head  three-fourths  as  wide  as  the  prothorax, 
with  well  developed  and  prominent  eyes,  the  frontal  foveae  very  deep, 
oblique  and  attaining  the  eyes;  antennae  long  and  slender,  rather  more 
than  half  as  long  as  the  body,  brown,  the  basal  joint  honey-yellow;  pro- 
thorax  not  a  third  wider  than  long,  the  sides  rounded  anteriorly,  oblique 
and  broadly  sinuate  basally,  the  angles  right  and  extremely  sharp  but  not 
everted;  base  and  apex  equal,  the  latter  broadly  sinuato-truncate,  with 
sharply  marked  but  not  prominent  angles;  surface  smooth,  finely  reflexed 
along  the  sides,  feebly  impressed  latero-basally  and  with  strong  close-set 
punctures  extending  to  the  sides,  obsolescent  medially,  the  stria  fine  but 
strong  and  entire;  elytra  two-fifths  longer  than  wide,  three-fourths  wider 


HARPALUSLE  225 

than  the  prothorax,  oblong,  very  obtuse  at  apex,  the  sinus  very  feeble 
but  evident;  striae  deep  and  sulciform,  the  intervals  convex  and  with  feeble 
iridescent  lustre,  the  discal  puncture  only  very  little  behind  the  middle. 
Length  (9)  3.8-4.2  mm.;  width  1.5-1.7  mm.  Isthmus  of  Panama 
(Colon).  Three  examples. 

The  hind  tarsi  are  somewhat  as  in  Stenolophus,  the  first  joint  as 
long  as  the  next  two  combined. 

*G.  isthmianus  n.  sp. — Much  smaller  than  bifossifrons  and  rather 
more  slender,  pale  rufo-testaceous  throughout,  each  elytron  very  faintly 
clouded  with  a  darker  tint  except  broadly  toward  all  the  sides  and  more 
narrowly  at  the  suture,  polished  throughout;  head  well  developed,  the 
eyes  rather  large,  prominent,  the  foveae  oblique  and  deeply  impressed; 
antennae  much  shorter  than  in  the  preceding,  with  very  much  shorter 
joints,  extending  only  to  the  basal  part  of  the  elytra;  prothorax  shorter, 
two-fifths  wider  than  long,  rounded  at  the  sides  anteriorly,  very  oblique 
and  straight  posteriorly,  becoming  sinuate  only  at  the  angles,  which  are 
scarcely  more  than  right,  sharp  and  slightly  prominent;  base  distinctly 
narrower  than  the  transversely  truncate  apex;  surface  nearly  as  in  the 
preceding;  elytra  oblong,  three-sevenths  longer  than  wide,  one-half  wider 
than  the  prothorax,  very  obtusely  rounded  at  apex,  without  evident 
sinus;  striae  deep,  intervals  strongly  convex  suturally,  less  so  externally, 
the  discal  punctures  more  posterior,  at  three-fifths;  hind  tarsi  shorter, 
very  slender,  about  two-thirds  as  long  as  the  tibiae,  with  the  basal  joint 
fully  as  long  as  the  next  two  combined,  the  claws  slender,  scarcely  at  all 
enlarged  at  base.  Length  (cf)  2.5  mm.;  width  i.o  mm.  Isthmus  of 
Panama  (Colon).  A  single  specimen,  taken  by  Mr.  Beaumont  and  sent 
with  examples  of  the  preceding  species. 

The  anterior  tarsi  of  the  male  are  only  feebly  swollen  and  joints 
2-4  have  beneath  two  rows  of  long  and  extremely  slender,  hair- 
like  squamules,  nearly  as  in  Amerinus,  one  at  each  side  of  each 
segment,  mingled  with  rather  coarse  setse,  so  that  they  are  difficult 
to  observe;  the  claws  are  moderately  diverging  and  slender  but 
are  more  or  less  swollen  at  base  internally.  The  middle  tarsi  are 
short  but  do  not  seem  to  be  modified  on  their  under  surface  and  have 
nearly  normal  claws.  It  is  certain  that  some  of  the  Central  Ameri- 
can species  placed  in  Bradycellus  by  Bates,  will  have  to  be  trans- 
ferred to  this  genus,  though  I  cannot  identify  any  one  of  them  with 
either  of  the  species  here  described. 

AGONIDUS  n.  gen. — This  is  a  genus  doubtfully  assumed  to  lie  in 
the  vicinity  of  Acupalpus,  being  so  different  in  facies  that  before  the 
discovery  of  the  criterion  afforded  by  the  number  of  supra-orbital 
setse,  it  would  probably  have  been  associated  with  Blechrus  rather 
than  Acupalpus.  The  body  is  subparallel,  with  very  large  orbicular 

T.  L.  Casey,  Mem.  Col.  V,  Oct.  1914. 


226  MEMOIRS  ON  THE  COLEOPTERA 

head,  moderate  eyes  and  posteriorly  oblique  sides  and  very  broadly 
rounded  hind  angles,  of  the  prothorax.  The  emargination  of  the 
mentum  is  large  and  deep,  broadly  parabolic  in  form,  without  trace 
of  tooth,  the  mouth  rather  abbreviated  between  the  mandibles  and 
the  mentum,  the  labial  palpi  rather  slender,  the  second  joint  almost 
as  long  as  the  third,  with  two  moderate  longer,  and  about  two  very 
short,  setae,  the  third  joint  very  gradually  acuminate,  the  fourth  of 
the  maxillary  about  twice  as  long  as  the  third  and  the  last  joint  of 
the  outer  maxillary  lobe  rather  short  and  thick,  moderately  acumi- 
nate. The  structure  of  the  upper  surface  of  the  head  is  unique  in 
the  subfamily  Harpalinee,  so  that  a  separate  group  may  have  to  be 
formed  for  this  genus,  perhaps  more  in  the  neighborhood  of  the 
Broscini.  There  is  beyond  doubt  but  one  supra-orbital  seta, 
situated  opposite  posterior  third  of  the  eye  and  at  some  distance 
from  the  latter;  the  epistoma  is  broadly  circularly  sinuate  and  it, 
as  well  as  the  frontal  surface  adjoining,  is  perfectly  plane  and 
without  trace  of  frontal  foveae  of  any  sort.  The  elytra  are  oblong, 
subtruncate  at  tip,  without  sharply  marked  striae,  these  being  in 
the  form  of  very  feeble  superficial  eroded  lines  in  the  position  of 
the  regular  striae,  the  scutellar  stria  distinct  and  rather  long,  par- 
allel; the  single  discal  puncture  is  unusually  posterior  in  position, 
being  at  apical  fifth,  the  line  of  lateral  foveae  widely  interrupted. 
The  hind  tarsi  are  very  slender,  the  basal  joint  rather  longer  than 
the  next  two  combined.  The  type  may  be  described  as  follows: 

*A.  cephalotes  n.  sp. — Rather  narrowly  suboblong,  moderately  con- 
vex, shining  throughout  (cT),  the  elytra  (9)  slightly  alutaceous,  deep 
black  throughout,  the  entire  legs  blackish  rufo-piceous,  the  antennae, 
extending  onto  the  base  of  the  elytra,  very  slender,  black,  the  basal 
joint  testaceous;  head  rounded,  very  nearly  as  wide  as  the  prothorax,  the 
surface  very  evenly  convex,  the  eyes  relatively  moderate  and  not  very 
convex;  prothorax  one-half  wider  than  long,  widest  near  apical  third, 
the  sides  rounded,  gradually  oblique  and  less  arcuate  posteriorly  and  very 
broadly  rounded  through  the  angles  to  the  transverse  median  part  of  the 
base,  the  latter  barely  three-fourths  as  wide  as  the  apex,  which  is  feebly 
sinuato-truncate,  the  surface  moderately  and  subevenly  convex,  not 
punctate  and  unimpressed,  finely  reflexed  at  the  sides,  the  stria  short, 
very  fine,  the  anterior  transverse  impression  fine  but  sometimes  visible, 
rather  close  to  the  apex;  elytra  oblong,  parallel,  with  feebly  arcuate  sides, 
two-fifths  longer  than  wide,  between  a  third  and  fourth  wider  than  the 
prothorax,  the  subtransverse  apices  truncate  or  just  visibly  sinuate;  side 
margins  only  very  finely  reflexed;  legs  slender.  Length  (cf  9  )  3.3-3.6 
mm.;  width  1.2  mm.  South  Africa  (Wellington,  about  50  miles  from 
Cape  Town).  Two  examples. 


HARPALIISME  227 

The  anterior  tarsi  of  the  male  are  only  very  feebly  swollen  and 
joints  2-4  have  beneath  a  double  line  of  rather  large,  scale-like 
plates,  one  to  each  joint  in  each  series;  the  middle  tarsi  seem  to  be 
slender  and  unmodified.  The  eyes  adjoin  the  buccal  opening  and 
there  is  no  lateral  modification  of  the  head  beneath. 

The  genus  Agonidus  may  be  closely  allied  to  Amblystomus  Er. ; 
if  so  the  latter  genus  is  widely  out  of  place  in  the  Munich  catalogue, 
though  properly  placed  by  Lacordaire. 

There  are  a  number  of  exceptions  to  the  system  of  characters 
defining  the  Acupalpini  as  here  considered,  such  as  the  punctiform 
or  elongate  and  not  obliquely  prolonged  frontal  fovese  of  Bradycidus

also  the  trisetose  second  labio-palpal  joint  in  Dicheirotrichus  and 
Catharellus ,  but,  as  the  summation  of  other  structural  features,  as 
well  as  the  general  habitus  of  the  body,  places  all  these  genera 
rather  plainly  in  juxtaposition  with  normal  members  of  the  tribe, 
these  exceptions  merely  serve  to  indicate  some  of  the  difficulties 
encountered  in  the  way  of  rigorous  tribal  definitions,  in  a  sub- 
family with  so  many  and  perplexing  cross  affinities  and  parallelisms 
in  all  directions.  As  previously  shown,  corresponding  inconsistencies 
occur  in  almost  every  tribe  of  the  subfamily. 

Trichocellus  Gangl. 

The  single  European  species  before  me,  which  is  probably  placidus 
Gyll.,  agrees  very  well  in  general  characters  with  our  own,  but  is 
rather  more  convex  and  with  more  deeply  impressed  striae,  these, 
in  fact,  becoming  sulciform  toward  the  suture;  it  is  certainly  not 
identical  with  any  of  the  moderate  number  of  American  species 
represented  in  my  collection,  which  without  much  doubt  are  also 
distinct  among  themselves.  Cognatus  Gyll.,  agrees  much  better 
with  our  common  northern  ruficrus  than  does  placidus,  but  according 
to  Dejean  it  is  smaller  in  size,  his  measure  being  3.5  mm.  in  length. 

The  body  in  Trichocelhis  is  moderately  convex,  subcuneiform  in 
outline,  the  elytra  being  a  little  broader  behind  than  before  the 
middle,  and  they  generally  have  minute  diffused  punctulation. 
bearing  very  small  erect  hairs,  either  over  the  entire  surface, 
recalling  Dicheirotrichus,  or  simply  near  the  edges;  it  is  virtually

and  stronger  micropubiferous  punctulation  and  in  the  male  there 
is  a  small  elongate-oval,  densely  pubescent  spot,  on  the  median  line 
near  the  centre  of  the  combined  basal  segments,  which  seems  to  be 
rather  constant  and  is  perhaps  homologous  with  the  small  pubescent 
spots  occurring  in  certain  species  of  Selenophonts,  although  they 
are  there  very  different  in  number  and  in  disposition.  The  species 
may  be  known  as  follows:

inference  merely,  as  I  have  not  seen  his  types  and  the  large  series

Glycerius  Csy. 

Although  so  different  in  the  elongate-oval,  very  convex  body, 
with  hard  dense  glabrous  integuments  and  obsolescent  elytral  striae, 
there  can  be  but  little  doubt  that  this  genus  is  more  closely  allied 
to  Trichocelhis  than  it  is  to  Bradycellus;  this  is  indicated  by  the  even 
sparse  punctulation  of  the  abdomen  and  by  the  male  abdominal 
and  tarsal  modifications.  The  head  is  relatively  much  smaller 
but  with  very  prominent  eyes,  the  antennae  rather  short,  mentum 
tooth  slender  and  very  acute,  the  ligula  feebly  dilated  at  apex,  the 
inner  lobe  of  the  maxilla  strongly  hooked  and  with  very  coarse 
cilia,  the  last  joint  of  the  outer  lobe  moderate  in  length,  gradually 
thicker  toward  base  and  very  finely  subulate  apically  and  the  second 
labio-palpal  joint  is  barely  at  all  shorter  than  the  third.  The 
prothorax  has  well  defined  basal  angles  and,  along  the  sides  in  the 
finely  reflexed  edge,  there  is  a  series  of  erect  setae  arising  from  very 
moderate  punctures  and  recalling  a  rather  similar  structure  in 
Nothopus  and  Hartonymus.  One  section  of  smaller  species  has  only 
one  marginal  seta,  the  others  having  become  obsolete,  but  a  careful 
inspection  of  the  fine  marginal  gutter  shows  a  feeble  irregular 
crenulatioh,  this  being  a  vestigial  remnant  of  the  normal  series  of 
definite  setigerous  punctures.  The  elytra  have  all  the  elytral 
striae,  excepting  the  deeply  impressed  sutural  and  feeble  eighth  and 
ninth,  completely  obsolete  or  sometimes  represented  by  very 
feebly  impressed  punctulation.  The  discal  puncture  and  scutellar 
stria  are  obsolete,  although  the  annuliform  fovea  of  the  latter  is 
well  developed.  The  anterior  tarsi  of  the  male  are  feebly  dilated 
and  have  beneath  joints  2-4  slender,  hyaline,  acutely  pointed  and 
decumbent  squamules,  extending  transversely  and  closely  out- 
ward from  the  median  line,  the  first  joint  with  only  one  or  two 
squamules  at  apex  and  not  transversely  arranged;  the  middle 
tarsi  are  slender  and  unmodified  and  the  posterior  slender,  with  the 
first  three  joints  decreasing  uniformly  and  rapidly  in  length.  There

are  on  the  median  line  of  the  male  abdomen,  near  the  base,  two  very 
small  rounded  and  densely  pubescent  spots,  analogous  to  that  of 
Trichocellus  but  still  smaller;  it  will  be  noted  that  they  are  arranged 
longitudinally  on  the  median  line  and  not  transversely  in  pairs,  as 
is  the  case  with  the  somewhat  analogous  spots  of  Selenophorus 
riparius  and  certain  allied  forms.  In  Trichocellus  these  spots 
are  usually  coalescent,  forming  a  single  elongate  spot.  The  species 
of  Glycerins  are  few  in  number  and  may  be  recognized  as  follows: 

Pronotum  plurisetose  along  the  lateral  edges 2

tending slightly  behind  the  prothorax,  the  first  three  joints  glabrous 
though  with  the  usual  setae;  prothorax  two-fifths  wider  than  long, 
the  sides  broadly  rounded,  feebly  converging  and  broadly,  very 
slightly  sinuate  posteriorly;  base  transverse  medially,  arcuately  and 
anteriorly  oblique  at  the  sides  to  the  somewhat  obtuse  but  distinct 
angles,  the  apices  of  which  are  but  little  blunted;  apex  truncate, 
narrower  than  the  base;  surface  smooth  and  polished,  with  a  very 
fine  stria,  the  foveae  small,  subelongate,  feebly  impressed  and  with  a 
few  minute  punctures;  elytra  fully  one-half  longer  than  wide,  a  third

The  species  of  the  second  section  of  the  genus  are  defined  above 
from  the  characters  given  by  Mr.  H.  C.  Fall  (Journ.  N.  Y.  Ent. 
Soc.,  1905,  p.  175).  Among  my  series  politus  is  easily  identified 
and  represented  by  numerous  examples,  but  whether  or  not  either 
of  the  others  is  present  among  individuals  taken  at  San  Diego  by 
Dunn,  or  in  Monterey  Co.,  at  Lake  Tahoe  or  Reno,  Nevada,  by 
myself,  I  am  uncertain;  they  are  very  closely  allied  among  them- 
selves. Mr.  Bates  in  the  "Biologia,"  defined  several  varietal  forms 
of  obsoletus,  but  it  would  take  large  and  carefully  collected  series 
to  demonstrate  the  validity  of  them,  even  as  subspecies;  obsoletus, 
however,  is  different  from  nitidus  and  valid  in  every  way  as  a  species.

Pelmatellus  Bates. 

This  is  an  isolated  genus  in  the  Acupalpini,  because  of  the  vesti- 
ture  of  the  anterior  and  middle  tarsi  of  the  male;  these  are  sub- 
equally  and  distinctly  dilated  and  the  soles  are  solidly  squamose  as 
in  the  Anisodactylini,  to  which  tribe  there  is,  however,  no  other 
suggestion  of  similarity.  In  fact  the  species  bear  a  close  resem- 
blance to  several  of  the  genera  allied  to  Bradycellus.  The  mouth 
parts  are  nearly  as  in  Glycerins,  but  the  emargination  of  the  men- 
turn  is  much  deeper  than  in  Bradycellus,  the  tooth  strongly  de- 
veloped. There  is  no  trace  of  abdominal  sexual  characters  in  the 
form  of  surface  modifications,  and  there  is  no  trace  of  the  diffused 
abdominal  punctulation  of  the  two  preceding  genera.  The  hind 
tarsi  are  slender,  with  the  first  three  joints  decreasing  uniformly 
and  not  very  rapidly  in  length,  the  first  much  shorter  than  the  fifth. 
Pelmatellus  is  moderately  numerous  in  species,  extending  in  range 
as  far  to  the  southward  as  Guatemala;  it  was  held  to  represent  a 
distinct  tribe  or  subfamily  by  Bates,  but  scarcely  merits  such  dis- 
tinction. The  two  species  in  my  collection  may  be  known  as 
follows : 

Form  oblong,  moderately  convex,  shining,  piceous-black  above  and 
beneath,  the  elytra  deeper  black,  the  suture  and  exterior  margin 
faintly  pallescent;  lustre  non-metallic  but  sometimes  faintly  greenish; 
legs  pale  testaceous;  head  mode'rate,  evidently  more  than  half  as 
wide  as  the  prothorax,  impunctate,  the  eyes  moderate,  prominent,  the 
oblique  foveae  distinct;  antennae  slender,  nearly  attaining  basal 
fourth  of  the  elytra,  fuscous,  paler  basally;  prothorax  one-half  wider 
than  long,  with  the  sides  subevenly  rounded,  widest  just  before  the 
middle,  apex  feebly  sinuate,  with  narrowly  rounded  angles,  narrower 
than  the  base,  which  is  finely  beaded  throughout,  transverse  medially, 
slightly  arcuate  laterally,  the  angles  very  obtuse  though  sharply 
defined,  not  rounded;  surface  evenly  convex,  smooth,  finely  reflexed 
at  rhe  sides  throughout,  with  a  rather  strong  entire  stria,  the  foveae 
shallow,  oblong,  widely  impressed  and  with  a  few  minute  punctures; 
elytra  oblong,  parallel,  with  feebly  arcuate  sides  and  rapidly  very 
obtuse  apex,  one-half  longer  than  wide  and  fully  a  fourth  wider  than 
the  prothorax,  the  sinus  rather  feeble  though  evident;  striae  fine, 
the  scutellar  oblique,  moderate  in  length,  the  intervals  flat;  discal 
puncture  at  two-thirds;  marginal  line  of  foveae  widely  interrupted; 
hind  tarsi  three-fourths  as  long  as  the  tibire.  Length  (cf  9  )  5.0-6.0

nearly  so,  the  legs  pale  testaceous;  head  almost  as  in  the  pieceding 
but  neaily  three-fifths  as  wide  as  the  prothorax;  antennae  rather 
slender  though  somewhat  strongly  compressed,  blackish,  the  two 
basal  joints  pale;  prothorax  nearly  one-half  wider  than  long,  through- 
out as  in  lncid-ns,  except  that  the  sides  are  rather  more  strongly 
arcuate;  the  very  obtuse  basal  angle-  are  not  only  not  rounded  but 
their  apices  are  minutely  prominent  in  the  type;  marginal  bead  of 
the  base  narrowly  interrupted  at  the  middle;  elytra  shorter,  two- 
fifths  longer  than  wide,  a  fourth  wider  than  the  prothorax,  parallel, 
with  broadly  arcuate  sides  and  finely  reflexed  edges,  the  apex  more 
produced  suturally,  the  sinus  much  stronger,  rather  deep;  striae 
extremely  fine,  shallow,  not  impressed,  the  scutellar  oblique,  feeble;

*sinuosus  n.  sp. 

Sinuosus  may  be  allied  to  stenolo phoides  Bates,  but  the  basal 
thoracic  angles  are  said  to  be  rounded  in  that  species  and  the  elytra 
rufescent  laterally.  The  Cloudcroft  examples  described  by  Fall  as 
turbatus,  are  exactly  similar  to  the  original  type  of  Bradycellus 
lucidus  Csy.,  which  is  not  alluded  to  by  Fall  in  his  article  on  the 
Tachycellus-like  genera,  though  plainly  printed  in  the  Henshaw  list. 

Episcopellus  n.  gen. 

The  type  of  this  genus,  the  Feronia  autumnalis  of  Say,  has  been 
shifted  back  and  forth  from  one  tribe  of  the  Harpalinae  to  another, 
in  a  most  unaccountable  manner.  It  is  plainly  a  Bradycellid  as 
maintained  by  LeConte,  who  however  unfortunately  placed  two 
true  Harpalids  with  it,  and,  as  the  base  of  the  prothorax  is  as 
strongly  and  completely  beaded  here  as  in  dichrous  and  vulpeculus, 
he  probably  for  that  reason  consented  to  have  it  leave  Bradycellus 
to  go  to  Harpalus  in  company  with  those  species.  The  body  is 
oblong,  rather  depressed,  the  head  moderate  and  perfectly  normal 
in  the  tribe,  except  that  the  frontal  fovese  are  obliquely  prolonged 
toward  the  eyes  only  for  a  short  distance,  and  the  labial  palpi  are 
unusually  long,  slender,  with  the  second  and  third  joints  equal, 
the  former  bearing  two  long  setae  and  one  or  two  that  are  short  and 
inconspicuous.  The  third  antennal  joint  is  somewhat  pubescent 
in  about  outer  half.  The  anterior  male  tarsi  are  very  moderately 
dilated,  the  intermediate  feebly  so  and  both  have  beneath  two 
approximate  series  of  large  elongate  decumbent  longitudinal 


236  MEMOIRS  ON  THE  COLEOPTERA 

squama.  The  hind  tarsi  are  slender,  the  basal  joint  as  long  as  the 
next  two  and  longer  than  the  fifth.  The  abdomen  is  feebly  punctu- 
late  at  base,  but  bears  no  special  sexual  marks  in  the  male.  The 
two  known  species  are  the  following : 

Form  oblong-suboval,  rather  feebly  convex,  polished  throughout,  deep 
black,  without  metallic  lustre  of  any  kind,  the  edges  of  the  pronotum 
and  elytra  diaphanously  paler;  under  surface  piceous-black,  the 
legs  testaceous;  head  smooth,  the  eyes  only  moderately  prominent; 
antennae  extending  fully  to  the  thoracic  base,  pale  testaceous  in 
color;  prothorax  not  quite  one-half  wider  than  long,  widest  anteriorly, 
where  the  sides  are  rather  strongly  rounded,  thence  feebly  oblique 
and  nearly  straight  to  the  basal  angles,  which  are  rather  obtuse  but 
sharply  defined  and  even  minutely  subprominent;  base  transverse, 
feebly  arcuate  laterally,  strongly  beaded  and  but  slightly  wider  than 
the  apex,  which  is  feebly  sinuate,  with  broadly  rounded  angles; 
surface  even,  smooth,  finely  and  evenly  reflexed  at  the  sides,  with  a 
rather  distinct  impressed  subentire  stria,  the  foveae  small  and  linear, 
rather  shallow  but  distinct,  barely  at  all  punctulate;  elytra  oblong, 
parallel,  with  feebly  arcuate  sides,  not  one-half  longer  than  wide, 
fully  a  fourth  wider  than  the  prothorax  and  rapidly  obtusely  ogival 
at  apex,  with  very  feeble  sinus:  striae  rather  fine  but  well  impiessed, 
the  scutellar  long,  subparallel,  the  discal  puncture  near  two-thirds; 
intervals  feebly  convex  throughout  the  width;  marginal  series  of 
fovea?  only  imperfectly  interrupted  medially.  Length  (cf  9  )  6.5- 
7.0  mm.;  width  2.6-3.0  mm.  Long  Island  to  Indiana. 

autumnalis  Say 

Form  more  oblong  and  elongate,  similar  in  coloration  and  lustre;  head 
and  antennae  nearly  similar,  the  former  rather  more  elongate,  the 
neck  distinctly  constricted-  prothorax  more  quadrate,  two-fifths 
wider  than  long,  widest  only  a  little  before  the  middle,  the  sides 
more  evenly  and  more  feebly  arcuate,  otherwise  nearly  similar, 
except  that  the  foveae  are  larger,  much  deeper  and  with  numerous 
scattered  distinct  punctures;  elytra  similar  throughout  but  longer, 
one-half  longer  than  wide  and  not  quite  a  fourth  wider  than  the 
prothorax,  the  scutellar  stria  still  longer  and  the  lateral  line  of 
foveae  more  completely  interrupted  medially;  hind  tarsi  not  quite  so 
slender  but  otherwise  similar.  Length  (9)7-2  mm.;  width  2.9  mm. 
District  of  Columbia nitescens  n.  sp. 

In  this  genus  the  emargination  of  the  mentum  is  notably  deeper 
than  in  the  true  Bradycellus,  the  tooth  similarly  strongly  developed. 
Nitescens  is  allied  rather  closely  to  autumnalis  but,  on  inspection 
with  a  series  of  the  latter  at  hand,  it  is  observed  to  be  more  elongate 
and  more  parallel  and  somewhat  larger  in  size;  the  prothorax  is 
more  quadrate,  much  less  transverse  and  is  less  inflated  at  the 
sides  anteriorly;  I  am  under  the  impression  that  the  type  was 
found  near  an  electric  light  of  the  city  in  July  some  years  ago. 


HARPALINVE  237 

Tachycellus  Moraw. 

No  one  seems  to  have  ever  had  more  than  a  vague  notion  as  to 
what  the  genus  Tachycellus  of  Morawitz  might  really  be.  Chau- 
doir  assigned  to  it  such  an  incongruous  mixture  that  it  was 
entirely  rejected  by  LeConte  in  his  treatment  of  our  minute  Har- 
palids  (Proc.  Acad.  Phila.,  1868,  p.  379).  Afterwards  G.  H.  Horn 
conceived  the  idea  that  it  included  all  those  forms  having  three 
glabrous  antennal  joints,  but,  as  pointed  out  by  Fall,  the  warrant 
for  that  assumption  is  not  clear.  There  exists,  however,  at  the 
present  time,  a  tradition  that  there  must  be  three  glabrous  antennal 
joints  and  furthermore  that  the  Harpalus  nigrinus  of  Dejean,  is  a 
typical  exponent  of  the  genus.  Accepting  this  as  true,  there  is  no 
other  species  than  nigrinus  that  can  properly  form  part  of  Tachy- 
cellus, because  of  a  peculiarity  in  the  form  of  the  frontal  foveae 
stated  in  the  above  table  of  genera;  the  other  species  placed  in 
Tachycellus  by  Horn,  will  therefore  have  to  form  another  genus,  to 
which  the  name  Triliarthrus  is  here  assigned.  The  mental  emargi- 
nation  is  relatively  narrow  and  deep  and  the  tooth  strong,  with  its 
acutangular  apex  blunt  at  tip.  The  ligula  is  feebly  dilated  apically, 
the  paraglossse  attached  nearly  throughout  its  length  but  having 
their  external  angle  at  apex  narrowly  prolonged,  as  in  some  of  the 
Anisodactylini.  The  assumed  type  of  the  genus  may  be  described 
as  follows: 

Form  oblong,  moderately  convex,  very  shining,  deep  black  and  without 
metallic  lustre,  the  under  surface  and  femora  black,  the  tibiae  pale, 
black  apically,  the  tarn  black;  head  rather  small,  barely  three-fifths 
as  wide  as  the  prothorax,  rather  constricted  at  base  and  with  moder- 
ately prominent  eyes;  antennae  slender,  black,  with  pale  basal  joint, 
the  third  joint  virtually  glabrous,  though  with  pallid  setae;  prothorax 
transversely  quadrate,  a  third  to  two-fifths  wider  than  long,  feebly 
rounded  at  the  sides  and  widest  anteriorly,  the  sides  very  feebly 
converging  and  straight  thence  to  the  basal  angles,  which  are  but 
little  more  than  right  and  sharply  marked  though  not  prominent; 
base  transverse,  strongly  beaded  laterally,  the  bead  interrupted  in 
median  half,  very  slightly  wider  than  the  sinuato-truncate  apex; 
surface  smooth,  finely,  evenly  reflexed  at  the  sides  and  with  a 
distinct  median  stria  from  the  obsolescent  anterior  impression  to 
the  base,  the  foveae  linear,  a  third  the  total  length,  rather  deep 
though  impressed  and  not  evidently  punctate;  elytra  relatively 
large,  one-half  longer  than  wide  and  one-half  wider  than  the  pro- 
thorax,  parallel,  with  feebly  arcuate  sides  and  obtusely  rounded 
apex,  the  sinus  almost  obsolete;  striae  very  fine,  not  deep  though

acute,  the  scutellar  extremely  short,  sometimes  obsolete;  intervals 
flat  or  nearly  so,  the  discal  puncture  strong,  at  four-sevenths,  the 
lateral  line  of  foveae  medially  interrupted;  hind  tarsi  short,  not 
three-fifths  as  long  as  the  tibiae,  the  first  joint  not  quite  as  long  as 
the  next  two  combined;  anterior  tarsi  (cf)  feebly  dilated  and 
biseriately  squamulose  beneath,  the  middle  tarsi  slender  and  un- 
modified. Length  (d71  9  )  4.7-5.2  mm.;  width  1.7-2.0  mm.  Cali-

This  species  seems  to  be  very  widely  disseminated  through  the 
colder  parts  of  North  America  but  is  not  very  abundant. 

Triliarthrus  n.  gen. 

Except  in  the  oblique  linear  form  of  the  frontal  foveae  and  in  a 
certain  difference  of  habitus,  due  to  the  arcuate  or  anteriorly  swollen 
sides  of  the  prothorax,  there  is  very  little  difference  between  this 
genus  and  the  preceding.  The  ligula  and  paraglossae,  mental 
emargination  and  tooth,  are  all  nearly  similar;  the  labial  palpi 
are  slender,  the  second  and  third  joints  exactly  equal  in  length. 
The  first  three  joints  of  the  antennae  are  glabrous,  the  third  with 
merely  a  single  corona  of  long  setae  at  apex  and  the  scutellar  stria 
is  generally  very  short,  sometimes  almost  obsolete  and  most  distinct 
in  kirbyi.  The  anterior  male  tarsi,  are  distinctly  dilated  and  have 
beneath  a  double  row  of  very  large  horizontal,  thin  and  hyaline 
plates,  which  are  transversely  plicate  but  not  divided,  the  middle 
tarsi  slender,  not  at  all  or  but  feebly  dilated,  though  usually  having 
a  double  series  of  small  slender  squamae;  the  hind  tarsi  are  slender, 
with  the  basal  joint  not  quite  as  long  as  the  next  two  combined  and 
generally  not  as  long  as  the  fifth.  The  species  are  moderately 
numerous  as  follows: 

Species  of  the  Atlantic  regions;  basal  angles  of  the  prothorax  variable.  .2

Georgia. 

Mr.  Fall,  who  examined  the  type  in  the  LeConte  collection, 
intimates  (N.  Y.  Journ.,  1905,  p.  171)  that  this  species  cannot  be 
referred  to  the  present  genus,  as  it  closely  resembles  Bradycellus 
rupestris  and  may  possibly  not  differ  from  it  specifically.  But  this 
conclusion  is  probably  due  to  hasty  or  inaccurate  observation, 
as  the  description  clearly  indicates  that  the  scutellar  stria  is  well 
developed;  it  is  wholly  obsolete  in  rupestris  and  allied  species. 
This  is  a  very  important  point  which  demands  further  comparative 
study  of  the  type. 

Catharellus  n.  gen. 

The  only  known  species  of  this  genus  resembles  those  of  Steno- 
cellus  in  habitus,  but  differs  in  some  important  features.  The 
body  is  similarly  elongate,  parallel  and  moderately  convex,  differing 
thus  from  the  more  ventricose  outline  of  Bradycellus,  but  there  is 
no  trace  of  the  important  annular  fovea  at  the  base  of  each  elytron, 
nor  of  the  basal  punctate  impressions  of  the  pronotum.  The 
emargination  of  the  mentum  is  moderately  shallow,  with  a  distinct 
and  acutely  angular  tooth.  The  labial  palpi  are  rather  slender, 
the  second  and  third  joints  equal  in  length,  the  former  convex, 
cylindro-oval  and  certainly  bearing  three  setae,  one  on  the  inner  and 
one  on  the  anterior  side  at  apex  and  one  on  the  anterior  side  behind 
the  middle,  the  third  joint  is  rapidly  subulate  at  tip  as  in  Brady- 
cellus and,  in  the  male,  has  a  large  rounded  cavity  medially.  This 
impression  seems  to  affect  the  males  of  most  species  of  the  Acupal- 
pini,  as  discovered  by  Horn,  but  I  have  also  occasionally  noted  it  to 
some  extent  in  females,  whether  it  is  due  in  part  at  least  to  post- 
mortem contraction  or  not  I  cannot  say.  The  type  may  be  de- 
scribed as  follows: 


HARPALIISLE  243 

Elongate,  subparallel,  moderately  convex,  black,  the  elytral  suture  and 
sides  posteriorly  feebly  rufescent;  under  surface  black,  the  legs  obscure 
rufous;  surface  rather  shining  though  feebly  alutaceous;  head  smooth 
and  convex,  fully  three-fourths  as  wide  as  the  prothorax,  with  promi- 
nent eyes,  the  vertex  with  a  feeble  central  puncture,  the  frontal 
foveae  deep,  oblique,  attaining  the  eyes;  antennae  notably  stout, 
black,  half  as  long  as  the  body,  the  basal  joint  alone  rufous;  prothorax 
a  third  wider  than  long,  widest  at  apical  third,  the  sides  strongly 
rounded,  oblique  and  feebly  arcuate  posteriorly,  finely  sinuate  very 
near  the  basal  angles,  which  are  obtuse  but  sharp  and  minutely 
prominent;  base  feebly  arcuate,  wholly  unmargined,  equal  in  width 
to  the  sinuato-truncate  apex;  surface  nearly  even,  with  feeble 
anterior  impression  and  very  finely  reflexed  along  the  sides,  some- 
what flattened  and  opaculate  latero-basally  but  impunctate,  the 
stria  fine  and  subentire;  elytra  one-half  longer  than  wide  and  two- 
fifths  wider  than  the  prothorax,  parallel,  with  feeble  arcuate  sides 
and  gradually  circularly  rounded  apex,  the  sinus  wholly  wanting; 
striae  fine  but  rather  strong;  intervals  flat  or  virtually  so  throughout, 
not  more  convex  at  tip;  discal  puncture  completely  wanting;  lateral 
line  of  foveae  broadly  interrupted  medially;  hind  tarsi  rather  short, 
slender,  three-fifths  as  long  as  the  tibiae,  the  first  four  joints  uni- 
formly decreasing  in  length,  the  first  much  shorter  than  the  fifth. 
Length  (d71)  4.3  mm.;  width  1.5  mm.  New  York  (Lake  Champlain), 
and  Ontario  (Montreal).  Lake  Superior, — LeConte.  [Geobcemis 
cordicollis  Lee.] cordicollis  Lee. 

The  anterior  tarsi  of  the  male  are  only  slightly  swollen  and  appear 
to  have  two  rows  of  elongate  inconspicuous  squamae  beneath,  the 
middle  tarsi  undilated  and  unmodified.  The  absence  of  a  discal 
puncture  on  the  elytra  is  an  important  character  not  specially 
alluded  to  by  LeConte,  although  no  puncture  is  mentioned  in  his 
description.  The  above  described  example,  which  I  took  at  Bluff 
Point,  may  be  smaller  than  the  type  of  LeConte,  though  the  pub- 
lished measurements  are  probably  excessive,  but  it  appears  to  be 
the  same  specifically;  the  Montreal  specimen,  recently  received 
from  Mr.  Knaus,  is  precisely  similar  to  the  New  York  representa- 
tive. It  is  a  remarkable  species  and  demands  generic  isolation  in 
my  opinion. 

Stenocellus  n.  gen. 

The  numerous  species  of  this  genus  may  be  distinguished  at 
once  from  Bradycellus  by  their  more  slender  elongate  parallel  and 
subdepressed  form.  The  prothorax  is  as  in  the  preceding  in  general 
form,  but  is  always  more  or  less  impressed  and  punctate  latero- 
basally  and,  as  in  Triliarthrus,  may  have  the  basal  angles  either 


244  MEMOIRS  ON  THE  COLEOPTERA 

minutely  prominent  or  rounded;  the  sides  are,  however,  never 
broadly  sinuate  basally,  with  sharply  marked  right  angles,  as  they 
are  in  the  next  five  genera  of  the  table  given  above.  The  elytra 
always  have  a  discal  puncture  well  behind  the  middle  and  a  clearly 
defined  annular  basal  fovea,  but  there  is  seldom  any  trace  of  a 
scutellar  stria  or  apical  sinus,  the  elytra  always  being  evenly  and 
circularly  rounded  at  tip;  the  lateral  line  of  foveae  are  widely  inter- 
rupted medially.  The  emargination  of  the  mentum  is  rather 
shallow,  the  tooth  narrowly  acute  and  well  developed.  The  labial 
palpi  are  of  quite  a  different  form  from  that  characterizing  the 
preceding  genus;  the  second  joint  is  unusually  short,  broad,  flat- 
tened, subtriangular,  with  the  anterior  edge  acute  and  bearing  two 
long  seta?,  the  third  joint  distinctly  longer,  inflated  basally,  finely 
subulate  apically  and  with  a  deep  impression  at  least  in  the  male. 
The  inner  lobe  of  the  maxilla  is  strongly  hooked  at  apex  and  the 
last  joint  of  the  outer  lobe  gradually  inflated  basally  and  drawn 
distally  into  a  long  slender  subulate  apex.  The  antennse  are 
slender  and  the  third  joint  does  not  have  any  of  the  very  short 
decumbent  pubescence  borne  by  the  following  joints,  though 
having  numerous  erect  setae.  The  frontal  fovese  are  deep  and  are 
prolonged  in  a  fine  oblique  line  to  the  eyes.  Male  sexual  characters 
will  be  described  under  severaj  specific  headings  below.  The 
species  are  very  numerous  but  rather  closely  allied  among  them- 
selves in  some  parts  of  the  series  and  especially  near  rupestris;  they 
are  widely  distributed  over  the  entire  continent  as  far  southward  as 
the  table  land  of  Mexico  and  are  generally  abundant  individually.

Kansas  (Sedgwick  Co.)  and  Texas.  Three  examples,  .festinans  n.  sp. 

The  species  from  Sonoma,  Cal.,  identified  above  as  symmetricus 
Mots.,  agrees  in  every  particular  with  the  original  description, 
including  size  of  the  body;  the  locality  also  is  virtually  identical. 
The  large  series  of  tantillus  at  hand,  by  reason  of  certain  diversity  of 
coloration,  length  of  elytra,  length  and  thickness  of  antennae  and 
other  features,  seems  to  indicate  that  there  may  be  some  distinct 
species  or  subspecies  that  are  now  confused,  but  further  extended 
series  from  carefully  recorded  localities  would  be  desirable  before 
coming  to  any  definite  conclusion.  I  am  unable  to  identify  the 
male  of  tantillus  from  tarsal  characters,  the  anterior  tarsi  being 
undilated  in  all  the  numerous  examples  examined,  but  the  male 
may  be  relatively  rare.  Larvatus  is  allied  to  rivalis  and  is  similar 
in  its  peculiar  pallid  coloration  and  very  prominent  eyes,  but  the 
size  is  very  much  smaller,  the  head  relatively  larger,  the  antennae 
shorter  and  more  slender  and  the  sides  of  the  prothorax  not  sinuate 
toward  base  as  they  are  in  rivalis.  Neglectus  is  unknown  to  me  and 
I  have  simply  transcribed  the  original  characters.  Bradycellus 
nigriceps  of  LeConte  may  be  a  Tachistodes  and  allusion  will  be 
made  to  it  under  that  genus.

258  MEMOIRS  ON  THE  COLEOPTERA 

The  position  of  the  following  species  is  problematical,  but  for  the 
present  it  may  be  attached  to  Stenocelhts,  although  differing  rad- 
ically in  the  form  of  the  prothorax: 

Bradycellus  subcordatus  Chd. — Similar  to  rupestris  but  with  dif- 
ferent form  of  prothorax;  eyes  more  prominent;  prothorax  slightly  broader, 
the  anterior  angles  not  at  all  rounded  at  their  tips;  sides  distinctly  sinuate 
in  posterior  half  and  falling  upon  the  base  in  a  right  angle;  base  very 
feebly  bisinuate,  more  transverse  near  the  angles;  surface  more  distinctly 
punctured,  especially  in  the  lateral  depressions;  elytra  slightly  broader, 
very  parallel,  flatter,  without  trace  of  scutellar  stria;  color  probably 
brown  when  mature.  Length  (9  )  4.75  mm. 

The  locality  is  not  stated,  but  as  the  type  was  sent  by  Mot- 
schulsky,  it  is  possibly  a  native  of  California;  it  is  said  by  Chaudoir 
to  be  best  placed  near  tantillus,  but  this  cannot  be  accurate,  as  the 
size  is  very  much  greater.  The  peculiar  conformation  of  the 
prothorax  and  size  of  the  body,  precludes  association  with  any 
Stenocellus  known  to  me  at  present. 

Amerinus  Csy. 

The  elongate  parallel  form  of  the  body  in  this  genus  strongly 
recalls  Stenocellus,  but  in  the  details  of  structure  the  two  genera 
are  only  remotely  connected.  In  Amerinus  the  emargination  of 
the  mentum  is  unusually  small  and  shallow,  the  long  sharply  pointed 
tooth  projecting  even  rather  further  than  the  angulate  lobes;  the 
middle  of  the  base  of  the  mentum  is  deeply  impressed,  the  impression 
binary.  The  ligula  is  very  slender  and  parallel  to  the  tip  and  the 
paraglossse  do  not  extend  quite  to  its  apex,  their  outer  angles 
divergently  prolonged,  these  processes  becoming  very  fine  and 
curved.  The  labial  palpi  are  quite  different  from  those  of  Steno- 
cellus, being  slender,  with  the  second  joint  slender,  parallel  and  as 
long  as  the  third.  The  second  joint  of  the  maxillary  palpi  is  notably 
thickened,  compressed  and  slightly  arcuate.  The  inner  lobe  of 
the  maxilla  is  extremely  hooked  at  apex,  the  point  prolonged  far 
beyond  the  long  coarse  setae  forming  the  fringe;  the  last  joint  of 
the  outer  lobe  is  also  very  long,  gradually  drawn  out  apically  into 
a  long  slender  subulate  point.  •  The  mandibles  are  long,  prognathous, 
rather  slender  and  feebly  arcuate  and  the  right  at  least,  and  possibly 
also  the  left,  has  a  small  acute  tooth  projecting  from  the  inner 
side  near  the  middle  of  the  length.  The  eyes  are  rather  small  and 


HARPALIN.E  259 

generally  but  feebly  convex,  the  frontal  foveae  long,  outwardly 
curved  and  extending  to  the  eyes  and  the  third  antennal  joint  is 
pubescent  like  the  fourth,  except  near  its  base.  The  anterior  tarsi 
of  the  male  are  moderately  thickened  but  scarcely  dilated  and  have 
beneath  two  rows  of  long  slender  squamiform  papillae,  one  in  each 
series  on  each  joint;  the  middle  tarsi  are  slender  and  apparently 
unmodified.  The  scutellar  stria  is  wanting,  though  the  fovea  is 
large  and  conspicuous.  There  are  four  setae  at  the  apex  of  the 
abdomen  in  both  sexes. 

Of  this  singular  genus  we  seem  to  have  three  species  as  follows: 

Elytra  very  long,  nearly  three  times  as  long  as  the  prothorax.  Color 
piceous-black  throughout,  the  legs  pale  testaceous;  surface  very 
shining;  head  rather  small,  elongate,  three-fifths  as  wide  as  the  pro- 
thorax,  the  eyes  more  convex  than  in  the  other  species;  antennae 
long,  very  slender,  pale  testaceous  throughout,  fully  half  as  long  as 
the  body;  prothorax  not  quite  as  long  as  wide,  widest  at  anterior 
two-fifths,  where  the  sides  are  somewhat  prominently  rounded, 
thence  broadly,  feebly  sinuate  and  feebly  converging  to  the  basal 
angles,  which  are  right  and  very  sharply  defined;  base  rectilinear 
throughout  and  very  slightly  wider  than  the  sinuato-truncate  apex; 
surface  very  feebly  convex,  finely  reflexed  and  diaphanous  at  the 
sides,  the  stria  deep  and  strong,  entire,  the  foveae  isolated,  linear, 
extending  for  two-fifths  but  not  quite  attaining  the  basal  margin, 
extremely  deep  and  cavernous,  the  bottom  slightly  rugose;  near  the 
apex  medially  there  are  a  few  fine  punctures;  elytra  three-fourths 
longer  than  wide,  parallel,  with  feebly  arcuate  sides  and  abruptly 
very  obtuse  apex,  two-fifths  wider  than  the  prothorax,  the  sinus 
broad  and  feeble  but  evident;  striae  deep,  subpunctate,  the  intervals 
convex;  discal  puncture  small,  near  two-thirds;  lateral  line  of  foveae 
very  widely  interrupted;  hind  tarsi  slender,  three-fourths  as  long  as 
the  tibiae,  the  first  joint  subequal  to  the  next  two  combined,  much 
shorter  than  the  fifth.  Length  (9)  4.5  mm.;  width  1.3  mm.

pale  testaceous  throughout,  slender,  nearly  three-fifths  as  long  as

deep  coarse  and  sulciform  entire  median  groove,  the  foveae  very  deep, 
abrupt,  elongate-linear,  a  third  the  total  length  and  attaining  the

Body  somewhat  less  slender,  shining,  piceous-black,  the  pronotum  at  apex 
and  base  and  the  elytral  suture  pallescent;  under  surface  nearly 
black,  the  epipleura  and  legs  testaceous;  head  nearly  as  in  the  pre- 
ceding but  with  dark  piceous  antennae,  the  two  basal  joints  testaceous; 
prothorax  but  just  visibly  longer  than  wide,  widest  at  two-fifths 
from  the  apex,  the  sides  more  strongly  rounded  than  in  linearis  and 
more  deeply  sinuate  posteriorly,  the  hind  angles  right  and  sharp; 
base  rectilinear  and  as  wide  as  the  truncate  apex;  surface  as  in 
linearis,  the  very  deep  basal  foveae  more  obliquely  prolonged  to  the 
basal  margin;  elytra  two-thirds  longer  than  wide,  two  and  one-half 
times  as  long  as  the  prothorax  and  two-fifths  wider,  nearly  as  in 
linearis  throughout,  except  that  the  striae  are  subpunctate,  the 
intervals  rather  more  convex  and  the  sinus  stronger  and  more  oblique ; 
the  discal  puncture  is  less  posterior  and  at  about  three-fifths  from 
the  base;  hind  tarsi  nearly  as  in  the  other  species.  Length  (cf)

In  all  the  species  the  side-pieces  of  the  prosternum  are  strongly 
though  not  very  densely  punctured  throughout  the  width  anteriorly 
but  not  basally.  Fuscicornis  resembles  linearis  but  is  somewhat 
larger,  with  less  elongate  and  laterally  more  sigmoid  prothorax 
and  darker  coloration  and  differs  especially  in  the  coloration  of  the 
antennae;  the  type  is  assumed  to  be  a  male,  although  the  only  trace 
of  inferior  squamulation  visible  on  the  anterior  tarsi  consists  of 
about  two  long  slender  and  coarsely  hair-like  squamae  on  the  fourth 
joint.  The  sexual  modifications  of  the  tarsi  are  rather  more  feeble 
in  this  genus  than  in  any  other  of  the  Eradycellid  genera  known  to 
me  at  present.

The  edentate  mentum  characterizing  this  and  all  the  subsequent 
genera  of  the  Acupalpini,  here  pertains  very  appropriately  to  a  genus 
resembling  Amerinus  in  outward  appearance,  being  slender,  even 
more  depressed  and  with  basally  sinuate  sides  and  sharp  right 


HARPALIN^:  261 

basal  angles  of  the  prothorax.  The  genus  is  however  very  peculiar 
in  having  three  series  of  setigerous  elytral  punctures,  exactly  as  in 
the  Selenophorini.  The  mental  emargination  is  very  evenly, 
circularly  sinuate,  the  ligula  very  slender,  detached  from  the  para- 
glossse,  which  are  of  a  form  completely  unlike  that  seen  in  Amerinus, 
they  being  elongate,  parallel,  concave  throughout  their  length  and 
with  their  apices  evenly  rounded.  The  labial  palpi  are  only  moder- 
ately slender,  the  second  joint  somewhat  compressed  and  shorter 
than  the  third,  the  apex  of  which  is  rather  rapidly  and  finely  subu- 
late. The  inner  lobe  of  the  maxilla  is  moderately  hooked  at  tip 
and  the  last  joint  of  the  outer  lobe  very  gradually  acuminate.  The 
only  properly  glabrous  antennal  joint  is  the  first,  the  second  to 
fourth  are  successively  more  closely  pubescent.  The  mandibles  are 
rather  short  as  usual,  the  eyes  somewhat  small  and  feebly  convex 
and  the  frontal  foveae  are  oblique  and  linear,  but  do  not  quite  attain 
the  eyes.  The  neck  is  rather  long  and  gradually  narrowed  basally. 
The  scutellar  stria  is  well  developed  and  the  lateral  line  of  foveae 
only  very  imperfectly  interrupted  medially.  The  anterior  tarsi 
of  the  male  are  rather  strongly  dilated,  the  joints  short,  transverse, 
sharply  angulate  and  with  a  long  stiff  seta  at  each  side  and  have 
beneath  joints  1-4  two  long  and  rather  narrow,  irregular,  hyaline 
squamules,  semi-erect  in  position  among  numerous  long  hairs; 
the  middle  tarsi  are  not  at  all  modified.  The  single  known  species 
is  the  following: 

Body  elongate,  slender,  very  depressed,  the  upper  surface  nearly  flat, 
shining,  testaceous,  the  head  and  the  elytra,  excepting  the  sides 
and  suture,  infumate;  under  surface  of  the  hind  body  somewhat 
piceous,  the  legs  pale  flavo-testaceous;  head  smooth,  with  unusually 
elongate  neck  behind  the  notably  small  and  feebly  convex  eyes, 
large,  nearly  four-fifths  as  wide  as  the  prothorax,  the  antennae  rather 
obscure  testaceous,  gradually  clearer  basally,  unusually  long  and 
thick,  nearly  two-thirds  as  long  as  the  body;  prothorax  not  quite  as 
long  as  wide,  strongly  rounded  at  the  sides,  the  latter  becoming 
rather  abruptly  deeply  sinuate  and  thence  parallel  to  the  base  in 
about  basal  fifth,  the  angles  right  and  very  sharply  defined;  base 
transverse,  much  narrower  than  the  sinuato-truncate  apex;  surface 
very  feebly  convex,  smooth,  the  stria  fine  but  broadly  impressed, 
entire  and  distinct;  foveae  narrow,  linear  and  rather  deeply  impressed 
in  basal  third,  not  attaining  the  base,  impunctate;  elytra  nearly 
one-half  longer  than  wide  and  two-fifths  wider  than  the  prothorax, 
the  sides  subparallel  and  broadly  arcuate,  the  apex  rapidly  very 
obtuse,  the  sinus  obsolete;  striae  rather  fine  and  feebly  impressed,  the

intervals  feebly  convex;  hind  tarsi  slender,  fully  two-thirds  as  long 
as  the  tibiae,  the  first  joint  rather  longer  than  the  next  two  combined 
but  not  quite  as  long  as  the  fifth.  Length  (cf)  3.3  mm.;  width  i.o 
mm.  Indiana, — -Levette.  [Badister  and  subsequently  JE,pus  testa-

The  form  of  the  prothorax  reproduces  very  nearly  that  of  the 
genus  Anthracus  Mots.,  but  the  chief  peculiarities  of  the  species 
are  the  triple  elytral  series  of  setigerous  punctures  and  the  long  and 
conspicuously  heavy  antenna?;  it  seems  to  be  but  seldom  taken  and 
may  actually  be  rare. 

Goniolophus  n.  gen. 

The  limited  number  of  small  species  forming  this  genus  are 
evidently  related  to  Philodes  and  Anthracus  by  the  form  of  the 
prothorax,  but  differ  from  the  former  in  having  only  a  single  series 
of  fewer  punctures  on  each  elytron;  in  Anthracus  there  is  only  the 
usual  single  discal  puncture.  The  emargination  of  the  mentum 
is  as  in  Philodes,  but  the  labial  palpi  have  the  second  joint  about 
as  long  as  the  third,  the  latter  more  gradually  and  less  finely  acu- 
minate apically.  The  ligula  is  very  narrow,  parallel  and  the  para- 
glossae  are  unattached  for  a  considerable  distance  from  its  apex; 
they  are  elongate  and  obtuse  at  tip,  nearly  as  in  Philodes  and  extend 
well  beyond  the  tip  of  the  ligula,  which  has  the  usual  two  very 
long  setae;  the  inner  lobe  of  the  maxilla  is  broadly  arcuate  and  much 
extended  at  apex,  the  inner  fringe  subspinuliform,  the  last  joint 
of  the  outer  lobe  very  long,  gradually  and  moderately  inflated 
basally,  thence  drawn  out  and  very  slender  for  more  than  half  the 
entire  length  distally.  The  neck  is  short,  the  eyes  large  and  very 
prominent,  the  frontal  foveae  oblique  but  not  attaining  the  eyes 
and  the  mandibles  are  short,  in  large  part  concealed  in  repose.  The 
antennae  are  slender,  the  first  two  joints  virtually  glabrous,  the 
third  pubescent  nearly  like  the  fourth.  The  scutellar  stria  is  long 
and  strong  and  the  lateral  line  of  foveae  is  distinctly  interrupted 
medially.  The  anterior  tarsi  in  the  male  are  nearly  as  in  Philodes, 
but  rather  less  strongly  dilated,  the  laterally  obliquely  angulate 
joints  1-4  each  having  two  larger,  very  long,  somewhat  trans- 
versely crumpled,  internally  serrulate,  hyaline  plates,  which  are 
obliquely  semi-erect;  the  fifth  joint  is  as  long  as  the  preceding  three 


HARPALIN^E  263 

combined;  the  middle  tarsi  are  slender  and  completely  unmodified. 
The  surface  of  the  body  is  much  less  depressed  than  in  Philodes  and 
even  somewhat  more  convex,  as  a  rule,  than  in  Anthracus. 

Of  the  three  described  species  I  have  only  one,  rectangulus  Chd., 
but  have  tried  to  interpolate  the  others  in  the  following  table  by 
means  of  the  published  descriptions;  the  generic  characters  out- 
lined above  are  from  lucens,  described  below  and  to  be  regarded 
as  the  type  of  the  genus:

bottom;  hind  angles  nearly  right  but  with  their  apices  evidently 
blunt;  base  transverse,  oblique  at  each  side;  elytra  elongate,  almost

feebly  sinuate  toward  base,  the  latter  feebly  arcuato-truncate, 
slightly  wider  than  the  feebly  sinuate  apex;  basal  angles  very  nearly

Body  more  slender,  only  moderately  convex,  much  smaller  in  size,

throughout,  sometimes  blackish  and  gradually  pallescent  at  the 
periphery;  elytral  suture  very  finely,  the  external  margin  more 
broadly,  posteriorly,  pallescent;  legs,  epipleura  and  prosternum

Not  rare.  [Acupalpus  rectangnlus  Chd.] rectangulus  Chd. 

The  number  of  setigerous  elytral  punctures  in  lucens  is  rigorously 
four  in  all  the  eight  series  of  the  four  individuals  at  hand.  In 
rectangulus  the  number  is  more  inconstant,  some  of  the  series  having 
four  and  some  five  punctures.* 

*  Since  the  above  matter  relating  to  Goniolophus  was  put  in  print,  I  have 
received  from  Mr.  Knaus  two  specimen?,  taken  near  New  Orleans,  La.,  of  a  species 
that  answers  very  well  to  the  description  of  longulus  quoted  in  the  table.  The  pro- 
thorax  is  less  sinuate  basally  than  in  the  others  and  the  basal  angles  are  more  obtuse 
and  blunt,  the  basal  foveae  deep,  oval  and  abrupt,  with  their  bottoms  closely  punctu- 
late. I  unhesitatingly  label  them  longulus,  although  there  are  plainly  four  foveae  in 
the  substrial  series,  the  three  mentioned  by  LeConte  being  therefore  doubtless  due 
to  an  error  of  observation.  The  species  is  very  different  from  lucens,  being  narrower 
and  more  elongate,  with  much  shorter  prothorax,  having  much  deeper  subbasal 
fovese  and  more  blunted  basal  angles. 


HARPALIN.E  265 

Anthracus  Mots. 

As  represented  by  consputus  Duft.,  this  essentially  palaearctic 
genus  bears  a  strong  outward  resemblance  to  Philodes  and  Gonio- 
lopJms,  having  similar  sinuously  basally  narrowed  prothorax,  with 
usually  sharply  denned,  right  or  nearly  right  basal  angles,  but 
having  only  the  single  discal  elytral  puncture  common  to  most  of 
the  genera  of  the  Harpalinae  and  not  series  of  such  punctures  as 
in  both  the  genera  mentioned.  The  emargination  of  the  mentum 
is  very  shallow  and  broadly,  evenly  sinuate  throughout  its  width. 
The  second  labio-palpal  joint  is  slightly  compressed  but  elongate, 
though  evidently  shorter  than  the  third  and  it  bears  two  very  long 
stout  setae;  the  third  joint  is  rather  slender,  very  gradually  narrowed 
apically  and  not  rapidly  subuliform  at  apex  as  it  is  in  Bradycellus 
for  example.  The  last  joint  of  the  outer  lobe  of  the  maxilla  is 
altogether  different  from  that  of  the  Bradycellids,  being  long  and 
extremely  slender  from  base  to  apex  and  with  feeble  even  arcuation 
throughout.  The  hind  tarsi  are  very  slender  and  only  moderate 
in  length,  the  basal  joint  not  as  long  as  the  next  two  combined. 
The  anterior  tarsi  of  the  male  cannot  be  described  at  present, 
as  my  examples  are  both  females.  The  antennae  are-  long  and 
slender,  with  the  usual  two  glabrous  joints  of  the  subfamily.  The 
elytral  striae  are  deep  and  the  scutellar  stria  is  well  developed. 

The  following  species  is  assigned  to  this  genus  without  misgiving, 
although  I  have  never  seen  it  in  actuality.  It  is  evidently  the 
descendant  of  a  migrant  from  the  palaearctic  fauna  by  way  of 
Siberia  and  Alaska,  in  recent  geologic  times,  and  forms  additional 
evidence  to  prove  the  semi-Asiatic  nature  of  the  true  Pacific  coast 
fauna : 

Form  much  elongated,  depressed,  shining,  piceousr  the  prothorax  and 
the  elytra  at  margin  and  apex  rufescent;  prothorax  subcordate,  not 
shorter  than  wide,  narrowed  posteriorly,  with  the  sides  subsinuate; 
hind  angles  right ;  surface  foveate  basally  at  each  side  but  only  slightly 
punctate;  elytra  slightly  wider  than  the  prothorax,  parallel  and  ob- 
liquely subsinuate  at  apex;  striae  rather  deep,  the  second  unipunctate; 
base  of  the  antennae,  palpi  and  legs  testaceous.  Length  "4  mm."

The  general  habitus  of  the  body  is  said  to  resemble  that  of 
Philodes  testaceus.  I  have  seen  no  record  of  the  original  unique 
type  having  been  duplicated  by  recent  collectors.

Acupalpus  Dej. 

As  represented  by  trivialis,  the  species  here  referred  to  the  genus 
Acupalpus,  which  is  very  much  more  developed  in  the  palsearctic 
than  in  the  nearctic  fauna,  have  the  body  very  small  in  size,  not 
much  elongated  and  rather  convex,  with  the  elytra  frequently 
wider  behind  the  middle  than  at  base  and  with  the  scutellar  stria 
short  or  altogether  wanting,  except  the  persistent  basal  fovea. 
They  form  a  group  quite  distinct  from  European  species  of  the 
meridianus  and  fiavicollis  type,  in  the  small  size  of  the  body,  shorter 
antennae,  less  rounded  basal  angles  of  the  prothorax  and  in  their 
uniformly  dark  colored  elytra.  In  trivialis  the  emargination  of 
the  mentum  is  evenly  parabolic  in  form,  rather  deep  and  the 
palpi  are  short,  the  second  joint  of  the  labial  slightly  compressed 
and  shorter  than  the  third,  which  is  rapidly  and  acutely  pointed 
at  apex.  The  ligula  is  very  slender,  parallel  and  shorter  than  the 
paraglossse,  the  latter  narrow,  rounded  at  tip  and  feebly  concave. 
The  inner  lobe  of  the  maxilla  is  slender  and  moderately  arcuate 
distally  and  the  last  joint  of  the  outer  lobe  is  somewhat  as  in 
Anthracus  in  its  very  slender,  gently  arcuate  form,  but  is  not 
quite  so  long.  The  mandibles  are  thick,  oblique,  nearly  straight 
externally  and  hooked  slightly  at  tip.  The  anterior  angles  of  the 
epistoma  are  sharp  and  abruptly  projecting.  The  oblique  frontal 
foveae  are  finely  prolonged  to  the  eyes.  The  hind  tarsi  are  slender, 
of  very  moderate  length  and  the  first  and  fifth  joints  are  subequal, 
scarcely  so  long  as  the  second  and  third  combined.  The  anterior 
tarsi  of  the  male  are  only  very  feebly  dilated  and  have  beneath  two 
approximate  series  of  very  thin  elongate  subdecumbent  hyaline 
squamae,  the  middle  tarsi  slender  and  unmodified.  The  abdomen 
is  finely,  sparsely  punctate  medially,  with  four  terminal  setae  in  the 
female  and  perfectly  smooth,  with  two  terminal  setae  in  the  male. 
The  five  species  in  my  collection  may  be  known  as  follows: 

Head  very  large,  only  slightly  narrower  than  the  prothorax  in  either  sex.  2

and  fully  as  long  as  the  eyes,  which  are  much  smaller  and  more 
feebly  convex  than  usual;  antennae  rather  stout,  as  long  as  the  elytra;

Form  much  stouter  but  otherwise  somewhat  similar,  very  shining,  piceous- 
black,  the  prothorax  throughout  testaceous;  legs  pale;  head  some- 
what larger,  three-fourths  as  wide  as  the  prothorax,  the  eyes  smaller 
but  prominent  and  somewhat  longer  than  the  neck;  antennae  obscure 
testaceous,  only  moderately  slender,  not  quite  as  long  as  the  elytra, 
the  joints  short  as  usual;  prothorax  as  in  carus,  except  that  the 
converging  sides  are  not  so  straight  posteriorly  and  the  obtuse  basal 
angles  evidently  rounded;  surface  nearly  similar  but  with  the 
impressed  part  near  the  angles  almost  completely  punctureless; 
elytra  barely  a  third  longer  than  wide,  feebly  inflated  posteriorly, 
still  more  broadly  obtuse  at  apex,  the  sides  broadly  arcuate,  only  a

trivialis  n.  sp. 

It  is  possible,  as  suggested  by  LeConte,  that  cams  may  be  the 
same  as  the  Trechus  immunis  of  Kirby,  but  there  are  evidences  of 
other  species  besides  those  here  described,  more  especially  one, 
represented  by  two  examples  labeled  "Ontario,"  which  are  a  little 
larger  in  size  and  of  more  elongate  form  than  the  typical  carus  and 
this  may  be  the  true  immunis.  The  species  in  the  carus  group  are 
rather  closely  allied  among  themselves.  In  hydropicus  the  head  is 
relatively  not  quite  so  wide  as  in  expertus,  but  is  very  peculiar  in 
its  long  neck  and  comparatively  small  and  feebly  convex  eyes. 


HARPALIN/E  269 

This  species  is  also  remarkably  distinct  in  its  very  short  and  strongly, 
posteriorly  inflated  elytra.* 

A  single  example  of  a  South  African  species,  which  I  took  at 
Wellington,  near  Cape  Town,  much  more  closely  resembles  these 
American  forms  than  it  does  the  European  species  of  the  meridianus 
type;  so  I  do  not  feel  disposed  to  suggest  a  subgeneric  name  for 
our  species,  although  they  are  so  strikingly  divergent  in  habitus 
from  the  normal  forms  of  the  genus. 

Stenolophus  Dej. 

This  is  one  of  the  largest  genera  of  the  Acupalpini  and  holds 
rather  closely  to  a  fixed  type  throughout  all  the  American  and  such 
of  the  European  species  as  I  have  had  opportunity  to  examine. 
The  head  is  usually  moderate  in  size,  the  eyes  well  developed  and 
rather  prominent  as  a  rule,  the  frontal  fovese  deep  and  oblique, 
though  generally  not  prolonged  to  the  eyes  and  the  antennae  are 
always  rather  long  and  slender,  with  the  usual  two  glabrous  basal 
joints  of  the  subfamily.  The  mandibles  are  short  and  thick,  their 
apices  finely  hooked  and  each  has  on  the  inner  margin  behind  the 
middle  a  small  and  sometimes  very  acute  tooth.  The  notch  of  the 
mentum  is  deep  and  evenly  sinuate  and  the  ligula  is  long,  gradually 
somewhat  expanded  apically,  the  paraglossae  adherent  about  to  its 
tip  and  with  their  outer  angle  prolonged  into  a  process  that  fre- 
quently curls  inward.  The  labial  palpi  are  long,  rather  slender, 
with  the  second  joint  barely  visibly  shorter  than  the  third  and 
bearing  three  very  long  setae,  two  near  the  middle  of  the  anterior 
margin  and  one  on  the  posterior  side  near  the  apex;  the  third  joint 
is  gradually  and  moderately  acuminate;  the  last  joint  of  the  maxil- 

*  The  measurements  published  by  LeConte  of  Acupalpus  hydropicus  (3  mm.)  and 
Goniolophus  reclangulus  (3-3.25  mm.),  are  plainly  excessive  and,  as  I  have  noted  many 
other  overdrawn  measurements  of  the  same  kind,  it  seems  certain  that  that  author 
unconsciously  fell  into  manipulative  methods  giving  erroneous  results.  If  the  object 
to  be  measured  be  held  above  the  scale,  its  projected  image  on  the  scale  will  cover  more 
units  of  length  than  the  actuality,  in  proportion  to  the  distance  between  the  scale  and 
the  object.  In  making  these  measurements  care  should  be  taken  to  place  the  scale 
close  to  the  object  and  in  such  a  way  that  bot
